The system shown is at steady state, steady flow. At inlet 1, the following are known: specific volume v1 = 0.00106 m3/kg, volume flow rate, V1 = 0.003 m3/s, and specific enthalpy h1 = 466 kJ/kg; at inlet 2, the following are known: density P2 = 986 kg/m2, pipe diameter d2 = 0.042 m, velocity Vel2 = 1.6 m/s, and specific enthalpy h2 = 702 kJ/kg. If at exit 3, the specific enthalpy is h3 = 1,487 kJ/kg, what is the total rate of change of enthalpy of the system? Express the answer in kW. 2 P2 d. Vel h2 w巧h Vi hi Control volume boundary h;
