The drag force, Fd, imposed by the surrounding air on a vehicle moving with velocity V is given by Fd= Cd ApV²/2 where Co is a constant called the drag coefficient, A is the projected frontal area of the vehicle, and p is the air density. An automobile is moving at V = 30 miles per hour with C = 0.28, A = 24 ft², and p = 0.075 lb/ft³. Determine the force, in lbf, and the power, in hp, required to overcome aerodynamic drag.

The gravitational acceleration on Mars is 3.72 m/s2. The density of water is 1000 kg/m3. Starting from these assumptions, estimate the specific weight of water on Mars in lbf/ft3. Note that when converting lbm (pounds mass) to lbf (pounds force), a unit conversion called gc is required (1 lbf = 32.2 lbm ft s-2). The conversion factor ensures that (under normal gravity), a 100 lbm load generates 100 lbf of gravitational force
Nitrogen gas is confined in a cylinder and the pressure of the gas is maintained by a weight placed on the piston. The mass of the piston and the weight together is 100 kg.

Determine: (a) The force exerted by the atmosphere, the piston and the weight on the gas if the piston is 200 mm in diameter. (b) The pressure of the gas. (c) If the gas is allowed to expand pushing up the piston and the weight by 500 mm, what is the work done by the gas in kJ?
