An ideal dual cycle has a compression ratio of 14 and uses air as the working fluid. At the beginning of the compression process, air is at 14.7 psia and 120F and occupies a volume of 98 in3. During the heat-addition process, 0.6 Btu of heat is transferred to air at constant volume and 1.1 Btu at constant pressure. Using constant specific heats evaluated at room temperature, determine the thermal efficiency of the cycle.

Question
An ideal dual cycle has a compression ratio of
14 and uses air as the working fluid. At the beginning of the
compression process, air is at 14.7 psia and 120F and occupies
a volume of 98 in3. During the heat-addition process, 0.6 Btu of
heat is transferred to air at constant volume and 1.1 Btu at constant
pressure. Using constant specific heats evaluated at room
temperature, determine the thermal efficiency of the cycle.
