Gas pressure testing time for unsteady gas flow
Input(s)
d: Internal Pipe Diameter (in.)
L: Length of Pipe (miles)
P: Initial Pressure (psi)
Output(s)
\(\mathrm{t}_{\mathrm{m}}\): Minimum Time Needed for Testing (h)
Formula(s)
\[
\mathrm{t}_{\mathrm{m}}=\frac{3 *\left(\mathrm{~d}^{2}\right) * \mathrm{~L}}{\mathrm{P}}
\]
