An air-standard dual cycle has a compression ratio of 9.1 anddisplacement of Vd = 2.2 L. At the beginning of compression, p1 =95 kPa, and T1 = 290 K. The heat addition is 4.25 kJ, with onequarter added at constant volume and the rest added at constantpressure. Determine: a) each of the unknown temperatures at thevarious states, in K. b) the net work of the cycle, in kJ. c) thepower developed at 3000 cycles per minute, in kW. d) the thermalefficiency. e) the mean effective pressure, in kPa.
