1-A steam power plant operates between boiler pressure of (42 bar) and condenser pressure of (0.035 bar ). Calculate for these limits the cycle efficiency; work ratio and SSC for each of the following cases : a - carnot cycle using wet steam. (anws : 0.432 , 0.739 , 4.9 kg/kw.hr) b - rankine cycle with dry saturated steam at entery to turbine. (anws :0.368, 0.996 , 3.64) c- rankine cycle of (b) when expansion process has isentropic efficiency of ( 80% ). ( anws : 0.294 ,0.995 , 4.56 kg/kw.hr). d- comments on your results.
