- In part 3 (polytropic) Why is T2 = 453.622 ?Please help in all subparts Correctly. (Gpt/Ai wrong ans not allowed)Please show the complete solution. (Example: Conversion of Units) How much heat in kJ must be transferred to 20 kg of air to increase the temperature from 20 Degree Celsius to 280 Degree Celsius if the pressure is maintained constant?
- a) Each cylinder in a four-cylinder car engine has a bore diameter of 63.53 mm and the stroke for each piston is 175.00 mm. Calculate the cubic capacity of the engine in cm3 and calculate the clearance volume per cylinder for a compression ratio, r, of 6.25. The bore diameter of each cylinder in a six-cylinder four-stroke internal combustion engine is 32 mm and the stroke of each piston is 125 mm. During testing, the engine runs at 1450 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 2.90 cm2 and a diagram length of 0.85 cm. The pressure scale on the indicator diagram is set to 165 kN/m2 per cm. Calculate the mean effective pressure (m.e.p) and the indicated power in kilowatts (kW) developed by this six-cylinder four-stroke engine. Give your answer to 2 decimal places. c) A hollow connecting rod has an inner diameter of 26.25 mm and is subjected to an axial tensile load of 500 MN.
