Thermodynamics (Carnot Cycle) One pound of a perfect gas which has a cp=300 ft-lbf/lbmR and k=1.25 is used as a working substance in Carnot cycle. At the beginning of isentropic compression, the temperature is 650R and the pressure is 40 psig. The pressure at the end of the isentropic co,pression is 210 psia. For this cycle, the overall expansion ratio is 5.0. For the cycle, calculate the efficiency.    Options:  a. 76.41% b. 48.63% c. 51.37% d. 23.59% e. None of the above
