The following cast iron pipe (carrying a flow of 3.4 cfs) becomes divided at point B and rejoins at point C. The elevation at the open reservoir surface is 560 feet. The elevation at point D is 350 feet. The pipe diameters and lengths are given in the table below. Calculate the pressure at point D in psi. Note that there is no outlet at D; the pipe continues on from there. Neglect minor losses. Hint: write out the energy equation from A to D. Use the Darcy Weisbach approach. Assume fully turbulent flow. Verify this assumption for just one of the pipes. If the assumption is not perfect, you do not need to iterate, you just need to verify and comment.
