Water enters a boiler at 18.33 °C and 137.9 kPa through a pipe at an average velocity of 1.52 m/s. Exit stream at a height of 15.2 m above the liquid inlet leaves at 137.9 kPa and 148.9 °C at 9.14 m/s in the outlet line. At steady-state, how much heat must be added per kg mass of steam? The flow in the pipe is turbulent.
