The water flow rate between tanks A and B in the figure below is to be increased by 25% (from 0 to 1.250) by the addition of a second pipe, as shown by the dotted lines running from point C to Tank B. If the elevation of the free surface in tank 4 is 35 ft above that in tank B. find the diameter, D, of this new pipe. Neglect the minor losses. The friction factor for the original pipe is 0.015, and for the added pipe is 0.025. 6-in, diameter 600 ft long 6-in diameter 500 ft long Diameter D, 500 ft long
