How do enthalpy effect the work of a turbine
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 … WebIt falls out of the flow, and the enthalpy decreases by an amount equal to the latent heat of condensation. The same thing should happen in reverse, when pressure is decreased, more water can join the airflow and this causes its combined total internal energy to increase.
