Define about the Puncture?

A dense ideal gas flows out of a small hole in a tire which has a pressure Po inside.

a) Calculate the velocity of gas outside the tire in the vicinity of the hole if the flow is laminar and stationary and the pressure outside is P1.

b) Calculate approximately this velocity for a flow of molecular hydrogen into a vacuum at a temperature T=1000 K. Express this velocity in terms of the velocity of sound inside the tire, S0.
