Water vapor initially at 3.0 MPa and 300°C is contained within a piston-cylinder. The water is cooled at constant volume until its temperature is 200°C . The water is then compressed isothermally to a state where the pressure is 2.5 MPa.
a. Locate states 1, 2, and 3 on a T-v and P-v diagram
b. Determine the specific volume at all three states,
c. Calculate the compressibility factor Z at state 1 and comment
d. Find the quality (if applicable) at all three states.
a heat pump utilizes a well-insulated compressor to compress r-134 from a saturated vapor at 160 kpa at a rate of 0.85
In the an ideal turbo jet, the engine is designed such that the turbine work is divided equally between the compressor and the propeller. The gas from the turbine discharges to a nozzle for additional thrust.
