## Homework Statement

Unit mass of a fluid at a pressure of 3 bar, and with a specific volume of 0.18 m^3/kg, contained in a cylinder fitted with a piston expands reversibly to a pressure of 0.6 bar according to the law p = c/v^2

, where c is a constant. Calculate the work done during the process. (Answer = 29.82 kJ)

## Homework Equations

## The Attempt at a Solution

Hi guys, its been a few years since i did any thermodynamics and I am struggling to remember how to solve this problem, iv been unsuccessfully trying to use the specific volume to get V2, and then W= P*(V2-V1).

Any help greatly appreciated ![/B]
