The pump shown in Fig. 4 adds a 15-ft head to the water (p= 1.94 slugs/ft, = 2.34 x 10-5 lbf-s/ft and y = 62.4 lbf/ft) being pumped from the upper tank to the lower tank. If the pipe has a roughness & = 0.003 ft, determine the flow rate Q. Use f = 0.03 as the initial guess then the following equation for the remaining iterations until f converges to the thousandth decimal place.
