Consider Example 14.4. Find the time required for the pressure in the container to drop by \(1 \%\) and by \(10 \%\), taking into account that as the interior pressure drops so does the leakage rate. Compare your result with the time estimated using the initial rate of pressure decrease found in Example 14.4.

Data From Example 14.4:-

Transcribed Image Text:

Helium gas is stored at 20C in a spherical container of fused silica (SiO2), which has a diameter of 0.20 m and a wall thickness of 2 mm. If the container is charged to an initial pressure of 4 bar, what is the initial rate at which this pressure decreases with time?
