8. Crude oil of specific gravity 0.82 and viscosity of 0.4 N-s/m2 is flowing at a rate of 8 ms through a pipe of diameter 0.9 m with a Darcy friction factor of 0.02. The head loss (m) due to viscous effects over 45 m of the pipe is most nearly: a. 2.0 m b. 4.0 m c. 6.0 m d. 8.0 m 9. Find the vertical force to hold the nozzle shown stationary. The fluid flowing through it is water, Ai 1.0 m2, A2 0.85 m2, Vi 20 m/s, P P gravity effects. a. 330 kN b. -330 kN c. 480 kN d. -480 kN and PPa30 kPa. Neglect 45° A2-P2 = patrn v,=20m/s 6 of 12
