WebThe Gibbs equation provides: d H = T d S + V d P = V d P δ W = d H = V d P ( isentropic d S = 0) Therefore V d P is isentropic shaft work from a flowing device. Important points: 1) … Webw= -Pext (delta V). You need the negative in front because when work is done "on the system" (which is positive), delta V (Vfinal-Vinitial) is negative (the ballon is compressed). So the two negatives make the whole term for work positive. Side note: remember that external pressure (Pext) is considered constant. pennington tapered window box
