Question

A large pump operates with a flow of 1000 KL/hr and develops

a pressure of 20 kg/cm2

. What is the power in HP that is delivered by the pump

please provide the solution also

Answer 1

Thus the power delivered by the pump is 745 HP

Explanation:

Theoretical flow work = Volume x pressure difference

Theoretical flow power = Discharge x pressure difference

Discharge = 1000 kl/hr = (1000 m^3)/(3600 sec)

Pressure difference = 20 kg/cm^2 = 2000000 Pa = 2 MPa

Gravity "g" = 10 m/s^2

So, theoretical flow power = 2000000 x 1000 /3600 Watt = 555555 Watt.

Now, 1 Horse Power (HP) = 746 Watt

So, theoretical flow power = 555555 Watt = 745 HP

Thus the power delivered by the pump is 745 HP
