4.1 m3 of a compressible gas in a piston-cylinder expands during an isothermal process to 11.2 m3 and 131 kPa. Determine the boundary work done by the gas in kJ to one decimal place.
In a well-insulated mixing chamber, 48 kg/s of warm air at 249 °C is mixed with 20.8 kg/s of colder air at 22 °C. Assume the air specific heat at constant pressure (cp) to be 1.1 kJ/(kg K). Determine the temperature of air at the outlet of the chamber in °C to one decimal place.
