q = mass x specific heat H2O x (Tfinal-Tinitial)
I would use mass = 17,000 and calculate q in J, then convert to kJ.
The radiator in your car uses either water or ethylene glycol (anti-freeze) to remove heat from the engine and dissipate it to the outside air. If the water recirculation rate is 17.0 kg per minute of water and the water temperature leaving the engine and entering the radiator is 86.0 C and the temperature of the water leaving the radiator and entering the engine is 46.0 C, then how much energy (kJ) is dissipated by the radiator per minute? The specific heat capacity of water is 4.18 J/g ·K. The units are kJ/minute. The error interval is +/- 5%.
