Question
A Diesel cycle releases 1750 J/mol of heat. The pressure and temperature at the begin- ning of the compression step are 1 bar and 50 °C,
Transcribed Image Text:A Diesel cycle releases 1750 J/mol of heat. The pressure and temperature at the begin- ning of the compression step are 1 bar and 50 °C,
and the pressure at the beginning of the expansion is 5 bar. The working fluid is an ideal gas for which Cp = 7R/2 and cy = 5R/2. (a) What is the tem- perature at the end of the adiabatic expansion? (b) What is the heat absorbed by the engine? (c) What is the compression ratio? (d) What is the work done during the compression step? Volume FIG. 1. Diesel cycle. Pressure
