Thermodynamics calculations are used to determine the right amount of heat load for a specific enclosure, while heat load refers to the amount of heat needed to keep an enclosure within the desired temperature range. The following heat loads for the Airbus A320 cabin have been estimated assuming steady state conditions. Using first law analysis and the principle of the conservation of energy determine the heat load for the airbus A320 based on the information in table Qu 1. Is the aircraft cabin in need of heating or cooling?
