What is Thermal Efficiency
22/05/2019Where Cp is the heat capacity at constant pressure and α is the coefficient of (cubic) thermal expansion. For ideal gas αT = 1 and therefore: dH = CpdT At constant pressure, the enthalpy change equals the energy transferred from the environment through heating: Isobaric process (Vdp = 0): dH = dQ → Q = H2 – H1 → H2 – H1 = Cp (T2 – T1)
