An ideal rankine cycle has saturated water vapor 1.5 mpa leaving the boiler. the turbine exhausts to the condenser operating at 80 kpa. find the specific work and heat transferred in each of the ideal cycle components and compute the efficiency of the cycle. compare your rankine cycle efficiency to the carnot cycle efficiency operating between the same temperatures.

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.
