Calculating Specific work

  1. Jun 11, 2013 #1
    1. The problem statement, all variables and given/known data

    Air is cooled in a process with constant pressure of 115 kPa. Before the process begins, air has a specific volume of 0.06 m^3/kg. The final specific volume is 0.03 m^3/kg. Find the specific work in the process.


    2. Relevant equations

    none.


    3. The attempt at a solution

    I think this equation can be used to solve this:

    Specific Work= integral (limit goes from 2 1) PxdV, but I don't understand how do I compute this. There aren't many Specific work related problems online, I've tried searching. Any help or pointers will be greatly appreciated! Thanks!

    Specific work is the amount of work done per unit mass of gas.
