An air-standard carnot cycle is executed in a closed system between the temperature limits of 350 and 1200 k. the pressures before and after the isothermal compression are 150 and 300 kpa, respectively. if the net work output per cycle is *

Pmax = 30MPa

The heat input required Qin = 0.706KJ

The mass of air m = 0.00296kg

Explanation:

The step by step solution to this problem can be found in the attachment below.

A Carnot cycle with specified temperature limits is considered. The maximum pressure in the cycle, the heat transfer to the working fluid, and the mass of the working fluid are to be determined. Assumptions

Air is an ideal gas with variable specific heats.

Analysis

(a) In a Carnot cycle, the maximum pressure occurs at the beginning of the expansion process, which is state 1.
