Problem.3
Steam initially at 0.3Mpa 250℃ is cooled at constant volume
(a) At what temperature will the steam become saturated vapor?
(b) What is the quality at 80℃ ? What is the heat transferred per Kg of steam in cooling from 250℃ to 80℃ ?
Problem .4
Steam initially at 1.5Mpa, 300℃ expands reversibly and adiabatically in a steam turbine to 40℃. Determine the Work output of the turbine per kg of steam?
Problem. 5
steam at 0.8Mpa, 250℃ and flowing at the rate of 1Kg/s passes into the pipe carrying wet steam at 0.8Mpa, 0.95 dry After adiabatic mixing the flow rate is 2.3Kg/s Determine the condition of steam after mixing the mixture is now expanded in a frictionless nozzle isentropic ally to a pressure of 0.4MPa. Determine the velocity of the steam leaving the nozzle. Neglect the velocity of steam in the pipeline.
