When the trigger is pressed, the compressed air expels the water through a
2 mm diameter tube at a velocity of 8 m/s. Estimate the temperature and
pressure in the air reservoir after 5s of operation. Air can be considered an
ideal gas with Cy=5R/2. You may neglect the presence of water in the vapor
phase. State any additional assumptions.
