The Hazen Williams equation can be used to calculate the pressure drop, P d (psi/ft of pipe) in pipes due to friction: P d = 4.52 Q 1.85 / ( C 1.85 d 4.87 ) Where Q is the flow rate (gpm), C is a design coefficient determined by the type of pipe, and d is pipe diameter in inches. Consider a 3.5-in.-diameter steel pipe with C = 120. Calculate the pressure drop in a 1000-ft-long pipe for flow rates of 250, 300, 350, 400, and 450 gpm. To carry out the calculation, first create a five-element vector with the values of the flow rates (250, 300 ,…). Then use the vector in the formula using element-by-element operations.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
