WebThe heat addition can be calculated by the equation Qinput = h 3 –h 2. Process 3-4 Isentropic expansion process. In the isentropic expansion process, the heated gas will be expanded adiabatically from the state 3 to 4 in a turbine. The gas will do the work and will lose the amount of energy that is equal to the work that will leave the system. WebA further implication of the energy equation is possible if a new property is introduced. Since p is constant, pdv is identical with d(pv) Thus the energy equation can be written as Q d u pv Q d pv du w w But specific enthalpy h = u+pv i.e. ∂Q = dh or in the integrated form Q = h 2-h 1 or for mass m, of a fluid
