Homework Help: Engine efficiency

  1. Sep 17, 2008 #1
    uh...just wondering but how do you find out the efficiency from a P-V graph?

    depends on the engine's process

    The figure is a PV diagram for a reversible heat engine in which 1.0 mol of argon, a nearly ideal monatomic gas, is initially at STP (point a). Points b and c are on an isotherm at T = 423 K. Process ab is at constant volume, process ac at constant pressure.

    How would I go about finding the efficiency from such a graph?
