In a steady-flow system, flows of mass and energy that cross the system boundary are steady. A steady fluid flow infers a flow of which parameters such as mass flow rate, pressure, temperature, etc. do not change in time. Given that mass flow rate, heat transfer rates, and work transfer rates are con_ _ dt _ Þdt, dQ ¼ Qdt, stant, the integration of the following equations dðmhÞ ¼ ðmh and dW ¼ W between initial state 1 and latter state 2 of the open system is straightforward.
Although in practice there are heat losses from turbine shell, these are minor with respect to work generation. A high enthalpy flow enters the turbine, work is produced, and a lower enthalpy flow exits the turbine. Isentropic efficiency is one of the most frequently used assessment parameters for turbines. Isentropic efficiency (s) is defined by the ratio of actual power generated to the power generated during an isentropic expansion. For an isentropic expansion there is no entropy generation; the turbine operation is reversible.
9 v (m3/kg) Carnot cycle for air as ideal gas: (a) power cycle, (b) reversed cycle (heat pump). 16 K. 5 EXERGY 27 Therefore, absolute temperature can be determined by the measurement of heat transfer at source and sink of a reversible heat engine. At the lowest limit, the temperature is 0 K, namely, when the reversible engine operates between reference temperature T0 at the source and absolute zero at the sink. 32) the heat delivered to the sink is nil and the heat absorbed from the source is completely transformed into work because in this idealized case the Carnot efficiency must be 1 (a limit never attainable).
