A monometer is attached to a tank of gas in which the pressure is greater than that of the surroundings. The manometer liquid is mercury, with a density of 13.50 g/cm3. The difference in mercury levels in the manometer is 2 cm. The acceleration of gravity is 9.81 m/s2. The atmospheric pressure is 93.0 kPa. Calculate in Pa the absolute pressure of the gas. Air is compressed in a piston-cylinder assembly from an initial state where pi=30 lbf/in2 and V1=25 ft3. The relationship between pressure and volume during the process is pV1.4=constant. For the air system, the work is -62 BTU. Determine the final volume. A power cycle with a thermal efficiency of 28% has Qin=600 Btu, what is Qout in Btu?
