A system receives 0.756 kg/s of a fluid at a velocity of 36.58 m/s at an elevation of 30.48 m. At the exit, at an elevation of 54.86 m, the fluid leaves at a velocity of 12.19 m/s. The enthalpies of entering and exiting fluid are 2791.2 kJ/kg and 2795.9 kJ/kg, respectively. If the work done by the system is 4.101 kW, determine the heat supplied.
