It is one page assignment contain calculation and explanations parts, A hand written answers with neat sketch should be scanned and submitted in pdf format only,find in the attachment the assignment file
and also I attached an example for this assignment but please do not copy from the example that I send
ASSIGNMENT-2 Due: 12th SEPT 2014 SEM314 PRINCIPLES OF THERMODYNAMICS (T2, 2014) Assignment – 2(10% of the total assessment of the unit) Instructions: Submit a hand written assignment on or before 12th SEPTMBER 2014 in DSO drop-box only; Provide a neat sketch where required; The filename must be your name only (“subrat-das.pdf”) 1 A Geelong Auto-mobile engineer claims to have designed an engine that takes in 105e3 kJ at a temperature of 400 K, rejects 42e3 kJ at a temperature of 200 K, and delivers 16 kWh of mechanical work. Would you advise investing money to put this engine in the market? Explain 2 A heat engine (HE) of 35% thermal efficiency is used to drive a refrigerator having a COP of 4, what is the heat input into the engine for each MJ removed from the cold body by the refrigerator? If this system is used as a heat pump, how many MJ of heat would be available for heating for each MJ of heat input to the engine? 3 A heat-engine (HE) and a heat pump (HE) works in particular arrangement (as shown below). The heat transfers from the HE and from the HP are used to heat the water of a multi-storied building. The efficiency of the heat engine is 27% and the COP of the heat pump is 4. Evaluate the ratio of the heat transfer to the circulating water to the heat transfer to the heat engine. 4 Explain why entropy is measure of disorder.
