    Estimating Energy Needed for Cooling Tunnel with 177.21kg/s Water Flow

    M is a parameter. I know the formula you mean but I think something about the Carnot heat engine is demanded: http://en.wikipedia.org/wiki/Carnot_heat_engine#Properties_and_significance But I can't apply the equations to my questions because I want to calculate the necessary power. Can...

    Estimating Energy Needed for Cooling Tunnel with 177.21kg/s Water Flow

    A cooling system that pumps 177,21 kg/s of water in a tunnel warmed by trains with an average thermal output of 37,125 mega watts. I have to estimate the energy which is necessary to run the system in order to cool down water with the mass M. Both in the general case and on the assumption that...
