Pr 2: (25 pt) Fuel oil (γ=48.0lbf/ft3,μ=2.0×10−5lbf−s/ft2) is pumped through the piping system shown below with a velocity of 4ft/s. The pressure 200ft upstream of the pump is 5 psig. The pipe lengths are shown in the figure, and the minor loss coefficients are as shown. The pipe diameter is 2.0 in, and the relative roughness, ε/D=0.001. (a) (5 pt) Compute the Reynolds number. (b) (5pt ) Compute the total frictional head loss. Use Eqn 6.49 to calculate the friction factor. (c) (10 pt) Determine the required head delivered by the pump. (d) (5 pt) If η=75% compute the bhp of the motor.
