Reduce the appropriate first law of thermodynamics : Water, initially a saturated vapor at 4 bar, fills a closed, rigid container. The water is heated until its temperature is 400 degree celc. KE and PE effects can be ignored.
Determine the thermal efficiency of the cycle : A steam power plant implements an ideal reheat Rankine cycle. Steam enters the inlet of thigh-pressure turbine at 8 MPa and 450 Celsius and the inlet of the low-pressure turbine at 0.5 MPa and 500 Celsius. The condenser operates at 10 kPa.
Air standard otto cycle with constant specific heats : A six cylinder engine runs at 4000 RPM with a compression ratio of 8:1 and a total clearance volume (total for all 6 cylinders) of 600 mL at TDC. The engine intakes atmospheric air at 100 kPA & 20C. The maximum temperature during the cycle is 1500 C
Ideal gas equation and van der waals equation : A rigid tank has a volume of 23.3 m3 and due to safety requirements its pressure should not exceed 105 bar. If the tank has been filled with 1000kg of water vapor and is heated to 360°C check to see if it is within safety requirements.
