Water enters a boiler at 18.33 °C (65°F) and 137.9 kPa (20 lb/in2 abs) through a pipe at a speed of 1.52 m/s. The vapor leaves the system at 137.9 kPa at a height of 15.2 m above the entrance height, at 148.9°C and 9.14 m/s. How much heat must be added to the system in steady state per kg of mass of vapor? The flow in both pipes is turbulent. Vapor V2 = 9.14 m/s 148.9 °C, 137.9 kPa 15.2 m Water V = 1.52 m/s 18.3 °C, 137.9 kPa
