Polytropic work equation
WebIt can also be expanded to include irreversible polytropic processes (see Ref ). Applicability. The polytropic process equation is usually applicable for reversible or irreversible processes of ideal or near-ideal gases involving heat transfer and/or work interactions when the energy transfer ratio (δq/δw) is constant for the process.

WebRearranging this equation a bit we get: Q = ΔU + W. Next, since pressure is equal to W ΔV, it can be denoted as: Q = ΔU + pΔV. Now, the ideal gas law can be applied (PV=nRΔT) and since pressure is constant: Q = ΔU + nRΔT. For the next step, we will assume that this number of moles of gas stays constant throughout this process: WebMay 28, 2024 · The polytropic work,𝑤 , as the measure of useful compression work, is the difference betw een the total enthalpy change and the area under the polytropic path on the T-s diagram be tween inlet ...
