WebMay 22, 2024 · From the first law of thermodynamics, the work done by turbine in an isentropic process can be calculated from: WT = h3 – h4s → WTs = cp (T3 – T4s) From Ideal Gas Law we know, that the molar specific heat of a monatomic ideal gas is: Cv = 3/2R = 12.5 J/mol K and Cp = Cv + R = 5/2R = 20.8 J/mol K WebThermal Efficiency of Brayton Cycle. In general, the thermal efficiency, η th, of any heat engine is defined as the ratio of the work it does, W, to the heat input at the high temperature, Q H.. The thermal efficiency, η th, represents the fraction of heat, Q H, converted to work.Since energy is conserved according to the first law of …
WebA turbine is a device that harnesses the kinetic energy of some fluid - such as water, steam, air, or combustion gases - and turns this into the rotational motion of the device itself. [2] Turbines are generally used in electrical …
