1. Determine the final air pressure, P2, in the container given the following
information:
A volume of air is reduced in size from 20 ft3 to 10 ft3, as shown in figure 20.
The given information is as follows:
P, = 0 psig (14.7 psia) P2 = ?
V = 20 ft3
V, = 10 ft

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
