Question 11 You are designing a gas turbine engine that must provide 1.91 kW of output power. The efficiency of the engine is 0.57 times the efficiency of an ideal (Carnot) engine with the same high and low temperatures. You have determined that you can supply 8.77 kW of input heat to the engine at a temperature of 595 K. What is the exhaust temperature you should design for the engine? Give your answer in Kelvin to at least three significant digits. Question 12 A small power plant is designed to generate (output) 8.32 kW of power (8.32x10³ J/s). The plant is powered by steam at 749 K with the exhaust at 325 K. This power plant is less efficient than an ideal engine, of course. It's efficiency is 51.1% of the efficiency of an ideal (Carnot) engine with the same high and lower temperatures. What is the magnitude of the heat that is exhausted by the engine each second? Give your answer in kJ (10³ J) to at least three significant figures. Your answer is a positive number, the magnitude of…

QUESTION 1 An Automotive Engineering company has à task to setup a diesel engine for a new vehicle model. The engine has four-cylinder, four-stroke and 3 liters of displacement volume that operates on the ideal diesel cycle with a compression ratio of 17 as shown in Figure 1. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg and an air-fuel ratio of 24. You are the engineer in the company is given the following task to analyze the engine characteristics based on constant specific heats at 500 K, a) Evaluate all the working temperatures and pressures al all points on P – V diagram. b) Evaluate the thermal efficiency of the cycle. c) If the engine is plan to operate at 3000 rpm, evaluate the power rating produce by the engine.
