During the power stroke of an engine, the work produced is 2520 kj/kg and the heat rejected through the cylinder is 570 kj/kg. If the internal energy increased by 120 kj/kg, determine the amount of heat received in kj/s if the working fluid flow at the rate of 3 kg/s.

According to the first law of thermodynamics, the heat received comes to the increase in the internal energy and work:
