+// Problem 8.6  (page no. 385) 

+// Solution

+

+//For the upper temperature of the cycle,we have 400C,and for 50kPa,the steam tables give us a saturation temperature of 81.33C.The efficiency of a Carnot cycle operating between the limits would be

+T1=400+273; //Celcius temperature converted to fahrenheit temperature

+T2=81.33+273; //temperature converted to fahrenheit temperature

+nc=((T1-T2)/T1)*100; //Efficiency of carnot cycle

+printf("The efficiency is %f percentage\n",nc);

+//In problem 8.1,

+nR=28.5; //Thermal efficiency of the cycle neglecting the pump work

+typen=(nR/nc)*100; //Type efficiency=ideal thermal efficiency/efficiency of carnot cycle operating between min and max temperature limits

+printf("The type efficiency of the ideal Rankine cycle is %f percentage\n",typen);
