OB JECTIVES To size pump in order to obtain its performance parameters such as differntial pressure, NPSHa, hydraulic power, efficiency and brakehorse power.
BASIS The following definition formed the basis for the pump calculation: 1. Total Suction Head, HD is defined as the suction vessel/reservoir pressure head (H SP) plus the static suction head (HSS) minus the friction head in the suction line (H SF) i.e. HS = HSP + HSS - HSF 2. Total Discharge Head (HD) is defined as the discharge vessel/reservoir pressure head (H DP) plus the static discharge head (HDS) plus the total friction head in the discharge line (H DF) i.e. HD = HDP + HDS + HDF 3. The Net Positive Suction Head Available (NPSHA) is defined as the suction vessel/reservoir pressure head, plus the static suction head minus the vapor pressure minus the suction friction head i.e. NPSHa = HSP + HSS - HVP - HSF It can also be expressed as the Total suction Head minus the Vapor Pressure i.e. NPSHa = HD - HVP 4. Static Suction Head, HSS is defined as the head resulting from elevation of the liquid relative to the pump center line. If the liquid level is above pump centerline, HSS is positive. If the liquid level is below pump centerline, HSS is negative. Negative HSS condition is commonly denoted as a “suction lift” condition 5. Static Discharge Head, HDS is defined as the vertical distance in between the pump centerline and the point of free discharge or the surface of the liquid in the discharge tank. 6. Friction Head is the head required to overcome the resistance to flow in the pipe and fittings It is dependent upon the size, condition and type of pipe, number and type of pipe and fittings, flow rate, and nature of the liquid.
CALCULATION Pipe Friction Calculation The average velocity in a pipe is calculated thus:
V =1273 . 23
where
V =
( 0 . 2777778×Q ) D2
Velocity in m/s
Q = Flowrate of fluid in m3/hr D = Internal Diameter of pipe in mm
Renolds Number is calculated as
Re=1000 where
( V ×D ) v
Re = Renolds Number (dimensionless) D=
Internal Diameter of pipe in mm
V=
Velocity in m/s
v = Viscosity in cSt If the Reynolds number is below 2000 than the flow is said to be in a laminar regime. If the Reynolds number is above 4000 the regime is turbulent. If it is between 2000 and 4000, it is in transition regime/flow. If the flow is laminar then the friction parameter f is calculated with the laminar flow
f=
64 Re
If the flow is turbulent then the friction parameter f depends on the absolute roughness of the pipe inner wall. Hence the friction parameter is calculated based on the Swamee-Jain equation
f=
0 .25
[ ( log10
ε 5 . 74 + 3 . 7 D Re0. 9
2
)]
where
f = Friction Parameter/Factor
ε=
Absolute Roughness of pipe, taken as 0.00015ft(0.05mm) for carbon steel
The general equation for pressure drop due to friction is the Darcy-Weisbach, where the pressure drop per unit length is expressed as
ΔPf L
where
ΔP f =
=1000 f
V D ×2 g
Pressure drop per unit length (m fluid/100m of pipe)
g =
Acceleration due to gravity, 9.8 (m/s2)
D =
Internal Diameter in mm
The pipe friction loss is therefore calculated as
Δ Pf (mfluid )=
(
ΔP f (mfluid ) L(100 mpipe )
)( ×
L(mpipe ) 100
)
Pipe Fitting Friction Calculation The friction loss for fittings depends on a K factor which can be found in textbooks.The fittings friction ∆F f can be calculated based on the following formula where K is a factor dependant on the type of fitting. Therefore
V2 ΔF f (mfluid )=K 2g where
ΔF f =
Friction loss in due to fittings (m fluid)
V =
Velocity in m/s
g =
Acceleration due to gravity m/s 2
Pressure Head Calculation The relationship between the fluid column height and the pressure at the bottom of the column is:
P= where
SG × H 10 . 197
P=
Pressure in bara
SG =
Specific Gravity
H=
Height of fluid in m
Pump Efficiency The pump efficiency is calculated as
[ ( )]
Eff = 1− where
0.8 ×100 Q 0. 25
Eff = Pump Efficiency % Q = Flowrate in gallons per minute (GPM)
Power The work performed by a pump is a function of the total head and the weight of the liquid pumped in a given time period. Pump output or hydraulic or water horsepower (WHP) is the liquid horsepower delivered by the pump and is expressed
WHP= where
SG×Q×ΔH 3960
WHP = Water horsepower or Hydraulic power in hp SG = Specific gravity Q =
Flowrate in GPM
∆H =
Total Differential head in ft
Pump input or brake horsepower (BHP) is the actual horsepower delivered to the pump shaft.
BHP= where
SG×Q× ΔH 3960×Eff
BHP = Brake horsepower in hp SG = Specific gravity Q
= Flowrate in GPM
∆H = Total Differential head in ft.
For reciprocating pumps the BHP is calculated thus:
BHP= where
Q× ΔP×100 Eff ×36
BHP = Brake horsepower in kW Q
= Flowrate in m3/hr
∆P = Total Differential Pressure in bara.

OB JECTIVES To size pump in order to obtain its performance parameters such as differntial pressure, NPSHa, hydraulic power, efficiency and brakehorse power.
BASIS The following definition formed the basis for the pump calculation: 1. Total Suction Head, HD is defined as the suction vessel/reservoir pressure head (H SP) plus the static suction head (HSS) minus the friction head in the suction line (H SF) i.e. HS = HSP + HSS - HSF 2. Total Discharge Head (HD) is defined as the discharge vessel/reservoir pressure head (H DP) plus the static discharge head (HDS) plus the total friction head in the discharge line (H DF) i.e. HD = HDP + HDS + HDF 3. The Net Positive Suction Head Available (NPSHA) is defined as the suction vessel/reservoir pressure head, plus the static suction head minus the vapor pressure minus the suction friction head i.e. NPSHa = HSP + HSS - HVP - HSF It can also be expressed as the Total suction Head minus the Vapor Pressure i.e. NPSHa = HD - HVP 4. Static Suction Head, HSS is defined as the head resulting from elevation of the liquid relative to the pump center line. If the liquid level is above pump centerline, HSS is positive. If the liquid level is below pump centerline, HSS is negative. Negative HSS condition is commonly denoted as a “suction lift” condition 5. Static Discharge Head, HDS is defined as the vertical distance in between the pump centerline and the point of free discharge or the surface of the liquid in the discharge tank. 6. Friction Head is the head required to overcome the resistance to flow in the pipe and fittings It is dependent upon the size, condition and type of pipe, number and type of pipe and fittings, flow rate, and nature of the liquid.
CALCULATION Pipe Friction Calculation The average velocity in a pipe is calculated thus:
V =1273 . 23
where
V =
( 0 . 2777778×Q ) D2
Velocity in m/s
Q = Flowrate of fluid in m3/hr D = Internal Diameter of pipe in mm
Renolds Number is calculated as
Re=1000 where
( V ×D ) v
Re = Renolds Number (dimensionless) D=
Internal Diameter of pipe in mm
V=
Velocity in m/s
v = Viscosity in cSt If the Reynolds number is below 2000 than the flow is said to be in a laminar regime. If the Reynolds number is above 4000 the regime is turbulent. If it is between 2000 and 4000, it is in transition regime/flow. If the flow is laminar then the friction parameter f is calculated with the laminar flow
f=
64 Re
If the flow is turbulent then the friction parameter f depends on the absolute roughness of the pipe inner wall. Hence the friction parameter is calculated based on the Swamee-Jain equation
f=
0 .25
[ ( log10
ε 5 . 74 + 3 . 7 D Re0. 9
2
)]
where
f = Friction Parameter/Factor
ε=
Absolute Roughness of pipe, taken as 0.00015ft(0.05mm) for carbon steel
The general equation for pressure drop due to friction is the Darcy-Weisbach, where the pressure drop per unit length is expressed as
ΔPf L
where
ΔP f =
=1000 f
V D ×2 g
Pressure drop per unit length (m fluid/100m of pipe)
g =
Acceleration due to gravity, 9.8 (m/s2)
D =
Internal Diameter in mm
The pipe friction loss is therefore calculated as
Δ Pf (mfluid )=
(
ΔP f (mfluid ) L(100 mpipe )
)( ×
L(mpipe ) 100
)
Pipe Fitting Friction Calculation The friction loss for fittings depends on a K factor which can be found in textbooks.The fittings friction ∆F f can be calculated based on the following formula where K is a factor dependant on the type of fitting. Therefore
V2 ΔF f (mfluid )=K 2g where
ΔF f =
Friction loss in due to fittings (m fluid)
V =
Velocity in m/s
g =
Acceleration due to gravity m/s 2
Pressure Head Calculation The relationship between the fluid column height and the pressure at the bottom of the column is:
P= where
SG × H 10 . 197
P=
Pressure in bara
SG =
Specific Gravity
H=
Height of fluid in m
Pump Efficiency The pump efficiency is calculated as
[ ( )]
Eff = 1− where
0.8 ×100 Q 0. 25
Eff = Pump Efficiency % Q = Flowrate in gallons per minute (GPM)
Power The work performed by a pump is a function of the total head and the weight of the liquid pumped in a given time period. Pump output or hydraulic or water horsepower (WHP) is the liquid horsepower delivered by the pump and is expressed
WHP= where
SG×Q×ΔH 3960
WHP = Water horsepower or Hydraulic power in hp SG = Specific gravity Q =
Flowrate in GPM
∆H =
Total Differential head in ft
Pump input or brake horsepower (BHP) is the actual horsepower delivered to the pump shaft.
BHP= where
SG×Q× ΔH 3960×Eff
BHP = Brake horsepower in hp SG = Specific gravity Q
= Flowrate in GPM
∆H = Total Differential head in ft.
For reciprocating pumps the BHP is calculated thus:
BHP= where
Q× ΔP×100 Eff ×36
BHP = Brake horsepower in kW Q
= Flowrate in m3/hr
∆P = Total Differential Pressure in bara.
