Please refer to the attached image. The new cat iron pipe carrying a flow of 0.3 ft³/s becomes divided at point B and rejoins at point C. The elevation at the reservior surface is 1300 feet. The elevation at point D is 560 feet. The pipe diameters and lengths are listed below. What is the pressure at point D? Neglect minor losses. Use the Darcy-Weisbach approach and assume fully turbulent flow. Verify this assumption for one of the pipes. If the assumption is not perfect, iteration is not necessary, just verify and comment.
