# 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.   ### Another question on Engineering Engineering, 03.07.2019 12:20
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.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
