Water in the rural areas is often extracted from underground water source whose free surface is 60 m below ground level. The water is to be raised 5 m above the ground by a pump.the diameter of the pipe is 10 cm at the inlet and 15 cm at the exit. Neglecting any heat interaction with the surroundings and frictional heating effects, a) what is the necessary power input to the pump for a steady flow of water at therate of 15li/sec in KW if pump efficiency is 85%? b) Specific speed when the motor has a torque of 205 N-m
