Heat Engine efficiency Problem

  1. May 31, 2014 #1
    Please help me with the question below with a proper explanation and also suggest me a reference to read for the same.
    Thank you!

    A solar collector receiving solar radiation at the rate of 0.6 kW/m2 transforms it to the internal energy of a fluid at an overall efficiency of 50%. The fluid heated to 350 K is used to run a heat engine which rejects heat at 313 K. If the heat engine is to deliver 2.5 kW power, the minimum area of the solar collector required would be?
