Adam - You've made a barometer. When you invert the glass of water and expose it to the tank, some of the water will escape into the tank - enough to allow a partial vacuum to form at the 'bottom' of the inverted glass. The air pressure between the glass and water will be lower than the...

The statement "the density of the leaking gas is always constant, at some time it will be higher than the density of gas in the container" is not accurate; the leak will slow and stop before the density inside is less than it is outside. The leak is driven by the pressure differential and...

I don't think density is a function of pressure in context of this problem, but am open to understanding why you do. The reason I don't think so is that density appears in eq 2 where Bernoulli's flow equation is applied: the left side of the equation where Pressure appears represents the...

Problem: Model a leaking pressurized cylinder volume filled with an ideal gas (density ρ and molecular weight w) charged to a pressure P at temperature T. The rigid cylinder of fixed volume V has a small leak (adiabatic – T doesn’t change significantly) of area a. The leak rate will diminish...
