Question

A gas undergoes the cyclic process shown in the figure. The cycle is repeated 100 times per minute. The power generated is, 240 W, 100 W, 60 W, 120 W

MARKS App · Accepted Answer

Work done per cycle is given by area of the PV curve = 1 2 × ( 30 - 10 ) ( 8 - 2 ) [from given] = 1 2 × 20 × 6 = 60 The cycle is repeated 100 times, so work done = 60 × 100 = 6000 As we know, P o w e r = W o r k d o n e T i m e t a k e n = 6000 60 = 100 W
