*NOTE:
For practical purposes, velocity is measured in KNOTS. One knot = 1.69
feet/second.
PROBLEMS:
Solve each problem. Make sure all units agree!!
 Find the total
air pressure detected by the pitot tube for a Cessna 182 airplane
flying at a pressure altitude of 10,000 feet (static pressure of 1455.6
lb/ft^{2 }) and a speed of 120 knots if the air density is 0.00162
slugs/ft^{3}.
 Find the difference
in pressure (p_{t}p_{s}) for the same conditions described
above if the airplane speeds up to 160 knots.
 If the total air
pressure for the same Cessna 182 is measured at 1478.7 lb/ft^{2},
what is the new velocity in knots of the airplane?
