QuestionDetails: A 1500-kW heat engine operates at 25% efficiency. The heatenergy expelled at the low temperature is absorbed by a stream ofwater that enters the cooling coils at 20 degrees C. If60 L flows across the coils per second, determine the increasein temperature of the water. Answer is 18 degrees Celsius QuestionDetails: QuestionDetails: A 1500-kW heat engine operates at 25% efficiency.

Explanation / Answer

   Given :    The heat engine operates at 25% efficiency , 75%heat will be rejected and this is given to the steam per every sec the heat given out Q =1500-kW * 75 / 100 .      for evergy secthe water entering the coils = 60L = 60*0.990                                                                       m = 59.4 kg          if the Qamount of heat is absorbed then the rise in temp os water          Q = mST S - specific heat T = Ti - Tf           initial temp - final temp.     Solve the above    I hope it helps you per every sec the heat given out Q =1500-kW * 75 / 100 .      for evergy secthe water entering the coils = 60L = 60*0.990                                                                       m = 59.4 kg          if the Qamount of heat is absorbed then the rise in temp os water          Q = mST S - specific heat T = Ti - Tf           initial temp - final temp.     Solve the above    I hope it helps you           initial temp - final temp.     Solve the above    I hope it helps you
