Hello Troy,
The math says the differential pressure (Pd, Ptotal - Pstatic) is
equal to 0.5*airDensity*V*V for a given velocity, V.
60 knots is roughly 100 ft/sec. Assuming a standard sea level density
and slogging through the ugly units conversions, the Pd would be ~2.65
PSI.
Pd = 0.5 * 0.002377 slug/ft^3 * 32.2 lbf s^2/ft / slug * 100 ft/s *
100 ft/s / 144 in^2/ft^2 (... told you it was ugly)
I hope that doesn't add more mud to the water.
