Current Attempt in Progress

Air is drawn into a wind tunnel used for testing automobiles as shown in the figure below. $($a$)$ Determine the manometer reading, $h,$

when the velocity in the test section is $56$ mph $.$ Note that there is a $1-$in$.$ column of oil on the water in the manometer. $($b$)$ Determine

the difference between the stagnation pressure on the front of the automobile and the pressure in the test section.

$($a$)h=$

ft

$($b$)p=$

$l\frac{b}{f}{t}^2$
