The drag force, Fa, imposed by the surrounding air on a vehicle moving with velocity Vis given by Fa= Ca ApV²/2 where C 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 = 40 miles per hour with Ca = 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.

Flow rate is expressed as gas velocity in cm/s. The gas is flowing through an open tubular column with an inner diameter of 0.25 mm. What volume flow rate (mL/min) corresponds to a gas velocity of 50 cm/s? (The volume of a cylinder is pr2 3 length, where r is the radius.)
The linear density of a rod of length 4 m is given by p(x) = 8 + 2Vx measured in kilograms per meter, where x is measured in meters from one end of the rod. Find the total mass of the ra kg
The atmospheric pressure at the time the video was taken was recorded by the National Weather Service as 30.10 inches of mercury, with the alternative measure of a sea level equivalent 1018.8 bar. What was the atmospheric pressure in the laboratory (we are only a few km from the Weather Service's station) in SI units? The standard unit of pressure is the pascal. For atmospheric pressure it is conventional to use kPa, kilopascal. Why is there a difference between the measured pressure locally and the sea level equivalent, apart from the continued use of imperial units for barometric pressure.

The Ekman number, Ek, arises in geophysical fluid dynamics. It is dimensionless parameter combining seawater density ρ, a characteristic length L, Seawater viscosity μ, and the Coriolis frequency Ωsinφ, where Ω is the rotation rate of the earth and φ is the latitude angle. Determine the correct form of Ek if the viscosity is in the numerator.
