Polytropic work done formula
WebThe work done in an adiabatic process can be derived from the formula for adiabatic process. PV ꝩ = Constant (K). This formula can be rewritten as P=KV-ꝩ In order to … Web1 day ago · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 − 2 = U + W 1 − 2. Before we can start modelling these one should know how to model work and heat for different processes. So let us do that first.

WebThere's the isometric process, also known as isochoric or isovolumetric, where the change in volume is 0, which meant, remember, that means no work can be done. The work was also 0 for an isometric process. And then there's the adiabatic process where no heat is allowed to flow into or out of the system.
