2.
A rigid tank (volume = V) containing an ideal gas
is initially at T, and P. At time zero, an exit pipe
(area = A) is opened and gas flows out of the tank
at velocity v = K(P – Pam)2, where P is the
pressure in the tank, Patm is the pressure of the
atmosphere outside the tank, and K is a constant.
The temperature of the gas in the tank is maintained
at T, during the process. The pressure and the
temperature of the gas exiting the tank are Patm and
T1, respectively. Assume that, inside the tank, the
pressure and specific volume do not vary with
position.

A. Derive a differential equation for the tank
pressure P as a function of time t.
B. Determine the time required for the tank
pressure to reach Patm:
