An air-standard dual cycle has a compression ratio of 16 and a cutoff ratio of 1.15. at the beginning of compression, p1= factor of 2.2 during the constant volume heat addition process. if the mass of air is 0.04 kg, determine 95 kpa and t 300 k. the pressure increases by a (a)-the heat addition at constant volume and at constant pressure, each in kj (b)-the net work of the cycle, in kj. (c)-the heat rejection, in kj (d)-the thermal efficiency

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
