Water at 70 F (p = 62.4 lbm/ft and u = 2.03x10$

Water at 70 F (p = 62.4 lbm/ft and u = 2.03x10$ lb.s/ft) is to be pumped through 2000 ft of pipe (cast iron, 8= 0.00085ft) from reservoir 1 to 2 at a rate of 1 ft'/s, as shown in the figure. If the pump delivers 80 hp to the fluid, what is the proper pipe size (diameter) in inches to maintain the 1 ft/s flow rate? Neglect the minor loss. 1 hp = 550 lbf.ft/s 120 Pump
