Question A$\mathrm{.}3$: A pitot$-$static tube is introduced in a supersonic flow. Determine the speed

of the flowing $($free$)$ stream if the tube reads a stagmation pressure of $130$ kPa $,$ a static

pressure of $110$ kPa and a static temperature of $519$ K $($in the proximity of the rube$),$ for:

$($a$)$ the gas is air
