Arankine cycle utilizes he at from a geothermal source; hence, steam is only available at 550°f and 900 psia into the turbine, whose efficiency is 92%. the condenser pressure is 2 psia, the pump efficiency is 87%, and there is a 150 psia pressure drop across the boiler. a) determine the enthalpies at all the states b) determine the cycle efficiency

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
