The Hazen Williams equation can be used to calculate the pressure drop, Pa (psi/ft of pipe) in pipes due to friction: Pa = 452Q185/C 1.85 d4.87 Where O 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; then use the vector in the formula using element-by-element operations
