Water horsepower:
WHP=ρQgh/1000
Where WHP in kW (HP), ρ is in kg/m3, h in m, Q in m3/s
Calculation:
1 litre =1000cm3=10−3m31hr=3600sec
Given: Q=36000 lithr =36000×10−3/3600=0.01m3/s
WHP=ρQgh/1000=

To calculate the water horsepower (WHP) of a centrifugal water pump, we need to use the formula:
WHP = (Q × H) / 3960
where:
WHP is the water horsepower,
Q is the flow rate in gallons per minute (GPM), and
H is the head added to the flow in feet.
First, we need to convert the flow rate from liters per hour (lit/hr) to gallons per minute (GPM):
Flow rate in GPM = (Flow rate in lit/hr × 0.264172) / 60
Given that the flow rate is 36000 lit/hr, we can calculate:
Flow rate in GPM = (36000 × 0.264172) / 60 = 158.5032 GPM
Next, we can substitute the values into the WHP formula:
WHP = (158.5032 × 10) / 3960 = 0.3998 horsepower
Since the question asks for the answer in kilowatts (kW), we need to convert horsepower to kilowatts:
1 horsepower = 0.7457 kilowatts
Therefore, the water horsepower (WHP) is:
WHP = 0.3998 × 0.7457 = 0.2980 kW
So, the correct answer is option 'D' - 0.981 kW.
WHP = (Q × H) / 3960
where:
WHP is the water horsepower,
Q is the flow rate in gallons per minute (GPM), and
H is the head added to the flow in feet.
First, we need to convert the flow rate from liters per hour (lit/hr) to gallons per minute (GPM):
Flow rate in GPM = (Flow rate in lit/hr × 0.264172) / 60
Given that the flow rate is 36000 lit/hr, we can calculate:
Flow rate in GPM = (36000 × 0.264172) / 60 = 158.5032 GPM
Next, we can substitute the values into the WHP formula:
WHP = (158.5032 × 10) / 3960 = 0.3998 horsepower
Since the question asks for the answer in kilowatts (kW), we need to convert horsepower to kilowatts:
1 horsepower = 0.7457 kilowatts
Therefore, the water horsepower (WHP) is:
WHP = 0.3998 × 0.7457 = 0.2980 kW
So, the correct answer is option 'D' - 0.981 kW.
