Problem 4: Air flows into an open system and carries energy at the rate of 100 kW. When the air leaves the system, the energy rate it carries is 250 KW. In the meantime, the system receives 350 kW power and negligible heat flux. If the system operates in a steady state and no power done by the system, determine the heat loss of the system in unit kW.
