Propane gas enters a continuous adiabatic heat exchanger' at 40°C and 250 kPa and exits at 240°C superheated steam at 300°C and 5.0 bar enters the exchanger flowing counter currently to the propane and exits as a saturated liquid at the same press..
a non-ideal brayton cycle with regeneration operates with incoming air at 22c and 0.1mpa. the compression ratio is 121
a manufacturer found hat the sales figure for a certain item depended on the selling price. the market research
Refrigerant 134a at a flow rate of 0.5 lb/s enters a heat exchanger operating at steady state as a saturated liquid at 0 0F and exits at 20 0F. A separate air stream enters at 120 0F and exits at 77 0F. The heat exchanger is insulated such that there..
An ideal Otto cycle has a compression ratio of 13.5, takes in air at 95kPa and 20°C and is repeated 940 times per minute. Using constant specific heats at room temperature, determine the thermal efficiency of this cycle
