A 10 kW electric heater is used to heat 2 kg of air contained in an insulated rigid tank from 400 kPa and 50 °C to 200 °C. The ambient air temperature and pressure is 20 °C and 100 kPa, respectively. (a) Draw and label a schematic of the system. Determine (b) the duration, in seconds, that the heater is turned on and (c) the exergy destruction (kJ) of the process. (d) Draw a T-s diagram of the process.
