An air-standard dual cycle receives air at 250C and 1 atmosphere pressure. The compression ratio is 15, and the cut-off ratio is 2.5. During the constant volume heat addition process the pressure doubles and the maximum temperature is 2300K. Determine the heat added in constant volume process. Find the heat added in the constant pressure process. Find the thermal efficiency.

An air-standard dual cycle receives air at 250C and 1
atmosphere pressure. The compression ratio is 15, and the
cut-off ratio is 2.5. During the constant volume heat addition
process the pressure doubles and the maximum
temperature is 2300K. Determine the heat added in constant
volume process. Find the heat added in the constant
pressure process. Find the thermal efficiency.
