. A large closed tank is filled with air under a pressure of 5.3 psi gage and at a temperature of 65°F. The air discharge into the atmosphere (14.7 psi) through a small opening in the side of the tank. Neglecting friction loses, compute the velocity of the air leaving the tank assuming (a) constant density of the air and (b) adiabatic flow conditions. Ans. 692 ft/sec, 728 ft /sec . For Problem 40 if the pressure were 10.0 psi, what would be the velocity for (a) and for (b)? Ans. 855ft/sec, 934 ft/sec

Question
40.) A large closed tank is filled with air under a pressure of 5.3 psi gage and at a temperature of 65°F. The
air discharges into the atmosphere (14.7 psi) through a small opening in the side of the tank. Neglecting
friction losses, compute the velocity of the air leaving the tank assuming (a) constant density of the air and
(b) adiabatic flow conditions.
ANSWER: 692 ft/sec, 728 ft/sec
41.) For Problem 40, if the pressure were 10.0 psi, what would be the velocity for (a) and for (b)?
ANSWER: 855 ft/sec, 934 ft/sec
