Question

When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = ?r^2P. The work done by the gas when the volume expands from volume V1 to volume V2 is W = ?_{V1}^{V2} P dV. In a steam engine the pressure and volume of steam satisfy the equation PV^{1.4} = k, where k is a constant. (This is true for adiabatic expansion, that is, expansion in which there is no heat transfer between the cylinder and its surroundings.) Calculate the work done by the engine during a cycle when the steam starts at a pressure of 120 lb/in^2 and a volume of 100 in^3 and expands to a volume of 1000 in^3. (Round your answer to two decimal places.) W = ______ ft-lb
