Doubt question:Find the rate \(v\) with which helium flows out of a thermally insulated vessel into vacuum through a small hole. The flow rate of gas inside the vessel is assumed to be negligible under these conditions. The temperature of Helium in the vessel is \(1000 K\).
My approach to the problem is stated as under.
The answer provided, unfortunately, turns out to be \(3.3 km/s\). Please help me finding my error out, thanks.
