Calculating Water Power, Discharge, Head, and Power of a Pump
What are the steps to calculate the water power of a pump, determine the new value of discharge and head when the speed of the pump is increased to 1000 rpm, and find the new value of power in kilowatts?
The water power of the pump can be calculated using the formula: Water Power = Discharge x Head x Specific Weight of Water To determine the new value of discharge when the speed of the pump is increased to 1000 rpm, we use the formula: Discharge1/Discharge2 = Speed1/Speed2 To find the new value of head when the speed of the pump is increased to 1000 rpm, we utilize: Head1/Head2 = Speed2/Speed1 The new value of power when the speed of the pump is increased to 1000 rpm is obtained by: Power1/Power2 = (Speed1/Speed2)^3
