## Homework Statement

A large tube filled with an ideal gas at pressure p

_{1}and temperature T

_{1}has a small break in it towards an envirronement at p

_{2}, with p

_{1}much larger than p

_{2}. What is the flow rate through the hole to the outside of the tube.

## Homework Equations

pv=rT

Δh+Δc

^{2}/2=δq-δl

h1 + c

_{1}

^{2}= h2 + c

_{2}

^{2}/2

## The Attempt at a Solution

The proces is adiabatic and isentropic so Δh+Δc

^{2}/2=0

Since it is a large tube it can be presumed that c

_{1}=0. Since p

_{2}is much lower than p

_{1}we can presume h

_{2}= 0.

Am I on the right track here?
