The air cushion car in Problem 29 is equipped with a 2 hp blower that is 70% efficient.

(a) What is the clearance between the skirt of the car and the ground?

(b) What is the air flow rate, in scfm?

A large tank containing water has a 51 mm diameter hole in the bottom. When the depth of the water is 15 m above the hole, the flow rate through the hole is found to be 0.0324 m3 /s. What is the head loss due to friction in the hole?
