Asteam power plant operates on an ideal regenerative rankine cycle with one open feedwater heater operating at 0.125 mpa. steam enters the first turbine stage at 15 mpa, 600 oc. condensate exiting the feedwater as saturated liquid at 0.125 mpa. the condenser pressure is 2.5 kpa. for isentropic processes in the two turbine stages and the pump, determine the followings: a) the net work of the cycle in kj/kg; b) the mass flow rate into the first-stage turbine, in kg-hr, if the net power developed for this power plant is 212 mw. c) the heat transfer into the working fluid through the boiler in kj/kg; d) the thermal efficiency of the cycle in %.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
