An air-standard dual cycle has a compression ratio of 8.6 and displacement of Va= 2.2 L. At the beginning of compression, p₁ = 95 kPa, and T₁ = 290 K. The heat addition is 4.25 kJ, with one quarter added at constant volume and the rest added at constant pressure. Determine: a) each of the unknown temperatures at the various states, in K. b) the net work of the cycle, in kJ. c) the power developed at 3000 cycles per minute, in kW. d) the thermal efficiency. e) the mean effective pressure, in kPa.

i need the answer quickly
ADVANCED CHEMISTRY! RATE WILL BE GIVEN! PLEASE WRITE THE COMPLETE SOLUTIONS A Steam at 400 deg C an 8,200 kilo Pascals enters a turbine and leaves at 10 kPa. What is the entropy of the leaving steam if the efficiency of the turbine is 0.76. Round the answers in to 2 decimal places. Hint: Turbine's efficiency is the ratio of work delivered by the actual turbine to the work delivered by an isentropic turbine (no entropy change) H (kJ/kg) S (kj/kg-K) 8200 kPa, 400 degrees 3137.6 6.3534 10 kPa, sat. liquid 191.832 0.6493 10 kPa, sat. vapor 2584.8 8.1511
