Question: ( 2 5 points ) Consider a shower head and an electric resistance system as the control volume ( steady - flow system ) shown

(25 points) Consider a shower head and an electric resistance system as the control volume (steady-flow system) shown below. This system heats the water (=1KgL) from 16C to 43C at a steady rate of 10Lmin. This system is connected to a heat exchanger for preheating liquid water before using the water head. Actually, water at 43C is to hot for taking a shower with.
2.1 For an incompressible liquid water (fluid) with density =1KgL and specific heat capacity cp=4.184kJKgoC, the steady-state mass flow rate of water is m=0.28Kgs.
True False
2.2 Assume that the heat exchanger is off. Treat the liquid water as an incompressible fluid with density =1KgL, specific heat capacity cp=4.184kJKgC and assume a steady-state water flow. In this case, the required electric power input along with T1=16C is Win=-18.83kW.
True False
2.2 The entropy generation during steady-state liquid water flow along with T1=16C is approximately Sgen=0.3623kJK
True False
2.3 The entropy generation along with T1=16C is Sgen=0.0623kJK.
True False
2.4 If T1=30C, then the required electric power input is Win,new=-9.07kW
True False
2.5 The entropy generation along with T1=30C is Sgen=0.0293kJK.
True False
