What is the heat transfer associated : Air in a piston-cylinder device is compressed from an initial state (temperature = 80 °C, pressure = 100 kPa, volume = 0.3 m3) to a final state (temperature = 250 °C, pressure = 600 kPa), during a polytropic process (n = 1.28094065700868). What is th..
Determine the temperature of the air at the exit : Air enters a pipe at 25 Celsius, 100 kPa at a flow rate of 36 m3/hr. A heater on the outside of the pipe draws 8 amps at a voltage of 120 V. All the heat from the heater is transferred to the air (well insulated and wall t is small).
