Air at 20oC and 1atm flows at 20 m/s past the flat plate shown below. A pitot tube placed 2mm from the wall, develops a manometer head h=16mm of Meriam red oil (SG = 0.827), measured relative to atmospheric pressure. Determine x, the downstream position of the pitot tube relative to the leading edge of the flat plate.
(hint: assume laminar and determine the velocity at the manometer inlet)
