Fuel oil (sp. wt = 48.0 lb/ft3, viscosity = 2.0 × 10-5 lb · s/ft2) is pumped through the piping system of Fig. P12.44 with a velocity of 4.6 ft/s. The pressure 200 ft upstream from the pump is 5 psi. Pipe losses downstream from the pump are negligible, but minor losses are not (minor loss coefficients are given on the figure).
(a) For a pipe diameter of 2 in. with a relative roughness e/D = 0.001, determine the head that must be added by the pump.
(b) For a pump operating speed of 1750 rpm, what type of pump (radial-flow, mixed-flow, or axial-flow) would you recommend for this application?
