Unformatted text preview: Determine the temperature and phase of the exiting stream. 4 Example 3: Work is produced by the expansion of steam in an adiabatic turbine. For the operating conditions below, determine the power available from the turbine. P = 20 bar T = 550 C P = 1 bar T = 150 C Mass flow rate = 1800 kg/hr 5 Example 4: Water flows at 1 kg/s through a horizontal pipe that abruptly changes diameter from 10 to 30 cm. Determine the resulting pressure change. 6 Example 5: Water is supplied to a gravity feed tank....
