Question

Derive the expression for maximum work done

Answer 1

Explanation:

Answer:Explanation:Here work done is calculated with the help of   Work = Pressure * change in volume

Work = -(-P – dP) – dV

Work = -(-PdV – dPdV)

For the expansion of the gas, the expansion will be taken into consideration, so integrate the over equation,  Integrate to o to wmax dw = integrate to v1 to v2 PdV

Ideal gas, P = nRT/V

Integrate o to wmax dw = integrate v1 to v2 nRT/V dt

On calculation, Wmax = -4.606 RT Log10 (V2/V1)
