WebMar 28, 2016 · I am completing a question that is requiring calculation of the work done in a polytropic process. In the worked solutions the work equation seems to be reversed for the answer, as can be seen in the screenshot- … WebBecause polytropic processes are general representations of thermodynamic pro-cesses, any quantities we calculate for a polytropic process will be a general equation for that quantity in all other thermodynamic processes. We proceed to nd the work and heat associated with a polytropic process. We start with the de nition of work: w= Z V 2 V 1 …

WebDerive w=Cv (T1-T2) from the moving boundary work equation for an ideal gas undergoing an isentropic process. Hints: 1. Assume a polytropic process. 2. Use the relationships: Cp-Cv = R and Cp/Cv = k. WebThe classical form of the first law of thermodynamics is the following equation: dU = dQ – dW In this equation, dW is equal to dW = pdV and is known as the boundary work. Then: dU = dQ – pdV In the isochoric process and the ideal gas, all heat added to the system will increase the internal energy. Isochoric process (pdV = 0): container to be able to reuse that name
