WebMay 22, 2024 · The first law of thermodynamics in terms of enthalpy show us, why engineers use the enthalpy in thermodynamic cycles (e.g. Brayton cycle or Rankine cycle).. The classical form of the law is the following equation: dU = dQ – dW. In this equation dW is equal to dW = pdV and is known as the boundary work.. Boundary work occurs … WebJul 11, 2024 · The pressure-volume work W v can generally be calculated by integrating the p (V) function of the polytropic process: Wv = – V2 ∫ V1p(V) dV. Thus, for calculating the work, the function p (V) must be … lexmark chat
