A pump raises the pressure of water, flowing at a rate of 0.1 m^3/s, from 70 kPa to 13 kPa. The inlet and exit areas are 0.07 m^2 and 0.04 m^2. Neglect any ΔPE. Assume the inlet and surroundings temperature to be 25 °C. Use the steady state SL model for water. The pump has an adiabatic efficiency of 75%.
Part A) Determine the power input (Ẇin).
Part B) Determine the exit temperature (T2).
Part C) Determine the rate of entropy generation (Ṡgen) in the pump. (kW/K)
