.85-120 Thermodynamics Tutorial 3 Problem 1. An inventor claims to have invented 4 engines, each of which operates between constant-temperature reservoirs of 400 and 300 K. Consider the 1st and 2nd laws of thermodynamics to evaluate the engines. For each engine, state and explain why it does or doesn't violate the 1st and 2nd Laws of Thermo. 1st law hint: Think quantity of work. 2nd Law hint: Think process efficiency.

An oil engine develops 300 kW and the specific fuel consumption is 0.21 kg/kWh. The exhaust from the engine is used in a tubular water heater, flowing through 25 mm diameter tubes, entering with a velocity of 12 m/s, at 340 °C and leaving at 90 °C. The water enters the heater at 10 °C and leaves at 90 °C, flowing in counter-flow to the hot gases. The air-fuel ratio of the engine is 20, and the exhaust pressure is...

Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...
