Explanation The specific speed of pump is dimensionless parameter which is used to characterize the operation of the pump at the optimum efficiency. The scaling law gives the relation of power, discharge and head with speed of pump. Write the expression speed and capacity for the pump. ....(I) Here, speed at point is speed at point is discharge at point is and discharge at point is Write the expression for head and speed for the pump. ....(II) Here, speed at point is speed at point is head at point is and head at point is Write the expression power and speed of the pump. ....(III) Here, speed at point is speed at point is power at point is and power at point is Since, there is no relation between specific speed and other parameters in scaling law, it can be said that pump specific speed are the extra parameters that are not necessary in the scaling laws for pumps. Write the expression to calculate the specific speed of pump. Here, speed is discharge is and head is The specific speed of pump is also used for designing of pump...
