The pipe system below consists of a 2-in-diameter pipe which is 50-ft-long in total. There is a flush entrance, two elbows, and a fully open gate valve. With the manufacturers pump curve given and taking f = 0.025, estimate the flow rate and corresponding pump head at the duty point. Take point B to be the outlet of the pipe (i.e. keep the term VB in this instance).
