ME 3322 — Thermodynamics Name: Unit: 2 Level: 2 ID: 0028.1 Date: nswer: 71.3 kg, 125 °C, 1.36 bar A fan drawing 1.5 kW of electrical power is located in a rigid, well insulated room with the dimensions 3 m × 4 m × 5 m. The room is filled with air initially at 20 °C and 1 bar. The fan runs at constant power for one hour. Determine the mass of the air in the room

Unformatted text preview: and the final temperature and pressure. Sketch the process on a T-v diagram. Neglect any changes in kinetic and potential energy, ignore the volume of the fan, and assume the fan stores no energy. Assume air is an ideal gas with the constant specific heats c p = 1.005 kJ/(kgK) and c v = 0.718 kJ/(kgK). A...
