Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheat rankine cycle at 1000 psia and 900°f and leaves as saturated vapor. steam is then reheated to 800°f before it expands to a pressure of 1 psia. heat is transferred to the steam in the boiler at a rate of 6 × 10^4 btu/s. steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser at 45°f. use steam tables. determine the following: (a) the pressure at which reheating takes place. psia (b) the net power output and thermal efficiency. % (c) the minimum mass flow rate of the cooling water required. lbm/s

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

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.
