+//INPUT
+T1=800;//temperature of reservoir 1 in K
+T2=400;//temperature of reservoir 2 in K
+Q1=1000;//energy absorbed from reservoir maintained at T1 in kJ
+Q2=400;//energy absorbed from reservoir maintained at T2 in kJ
+W=1000;//work delivered by the heat engine in kJ
+T3=300;//temperature of the sink in K
+
+//CALCULATION
+Q3=(Q1+Q2)-W;//calculation of the energy rejected to the sink using the first law of thermodynamics in kJ
+clausius_inequality=(Q1/T1)+(Q2/T2)-(Q3/T3);//application of the second law of thermodynamics in the form of the Clausius inequality using Eq.(5.28)
