water is pumped from the adjacent lower pool to the upper pool with a volume flow of 0.03m^3/s. The height difference between the pools is 45m and the surface of both pools is affected by the same amount of atmospheric pressure (1bar) with an air temperature of 20C. If the electric power taken from the electric network by the electric motor of the pump is 20Kw, then what is the amount of heat absorbed by the environment
