Activity 11 - Review for Midterm Steam at a pressure of 9 bar (hf = 743 kJ/kg , hfg = 2031 kJ/kg) is generated in an exhaust gas boiler from feed water at 80*C (h = 334.9 kJ/kg). If the dryness fraction of the steam is 0.96, determine the heat transfer per kilogram of steam. If wet saturated steam at 8 bar (hfg = 2048 kJ/kg) requires 82 kJ of het per kg of steam to completely dry it, what...

7. Steam leaves an industrial boiler at 827.4kPa and 171.6°C (hf = 727.25 kJ/kg, hfg = 2043.2 kJ/kg ). A portion of the steam is passed through a throttling calorimeter and is exhausted to the atmosphere when the calorimeter pressure is 101.4 kPa and a temperature of 115.6°C (h= 2707.6 kJ/kg ). How much moisture does the steam leaving the boiler contain ? 8. During the polytropic process of an ideal gas, the state changes from 138 kPa and 5°C...

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...
