Efficiency of an engine operating condition to Carnot cycle is equal to ? = 0.45. Temperature and specific volume of the gaseous working medium at the beginning of isentropic compression are T1 = 600 K and v1 = 0.5 m³/Kg respectively. Find the gas properties at all other characteristic points of the cycle and the amount of heat released during isothermal compression. Assume that the mass of 1Kg of the gas undergoes the sequence of processes corresponding to Carnot cycle. The specific volume of the gas at the end of isothermal expansion is doubled in comparison to specific volume at the end of the adiabatic compression. The particular gas constant and isentropic exponent of the gas is R = 287 KJ/KgK and K= 1.4 respectively. Draw the cycle on p-V and T-s diagram.

Carnot engine operating

The oceans in the tropics have substantial surface-to-deep-water temperature gradients. Depending on location, relatively constant temperature differences of 15 to 25oC can obtain for depths of 500 to 1.000 m. This provides the opportunity for using cold (deep) water as a heat sink and warm (surface) water as a heal source for a power cycle. The technology is known as "OTEC (Ocean Thermal Energy Conversion).(a) Consider a location where the surface temperature is 27oC and the temperature at a depth...

An engine operates in a Carnot cycle. At point A in the cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1,400 kPa, a volume of 10.0 L, and a temperature of 720 K. The gas expands isothermally to point B and then expands adiabatically to point C, where its volume is 24.0 L. An isothermal compression brings it to point D, where its volume is 15.0 L. An adiabatic process returns the gas to point A....
