Calculate the plume rise from a 0.5 meter diameter smokestack emitting 5 m3/s of air at 500 degrees celsius. data from a nearby meteorologic station indicates the average wind speed in the area is 5 m/s, the environemntal temperature at the height of the stack is 280 degrees celsius and the potential temperature gradient is -0.01 degrees/m.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
