Water at 20 bar, 400°C enters a turbine operating at steady state and exits at 1.5 bar. Stray heat transfer and kinetic and potential energy effects are negligible. A hard-to-read datasheet indicates that the quality at the turbine exit is 98%. Can this quality value be correct? If no, explain. If yes, determine the power developed by the turbine, in kJ per kg of water flowing

Steam enters a turbine operating at steady state at 2 MPa, 360 °C with a velocity of 52 m/s. Saturated vapor exits at 0.1 MPa and a velocity of 35 m/s. The elevation of the inlet is 1 m higher than at the exit. The mass flow rate of the steam is 21 kg/s, and the power developed is 5 MW. Let g = 9.81 m/s2. Determine the area at the inlet, in m2.

A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...
