Problem 2.74

A thermally insulated vessel with gaseous nitrogen at a temperature t=27∘Ct=27^{\circ} \mathrm{C} moves with velocity v=100 m/s.v=100 \mathrm{~m} / \mathrm{s} . How much\mathrm{much} (in per cent) and in what way will the gas pressure change on a sudden stoppage of the vessel?

Reveal Answer
 Increases by Δp/p=Mv2/iRT=2.2%, where i=5\text { Increases by } \Delta p / p=M v^{2} / i R T=2.2 \%, \text { where } i=5
