Moody Chart ProblemsOil (ρ= 900 kg/m3and ν= 0.00001 m2/s) flows in a commercial steel pipe of 5-mm diameter at a rate of 0.01 lit/s. Determine the friction factor for this flow.8.5R. Water flows in a smooth plastic pipe of 200-mm diameter at a rate of 0.1 m3/s. Determine the friction factor for this flow.8.6R. After a number of years of use, it is noted that to obtain a given flowrate, the head loss is increased to 1.6 times its value for the originally smooth pipe. If the Reynolds number is 106, determine the relative roughness of the old pipe.Compute the loss of head and pressure drop in 200 ft of horizontal 6-in-diameter Galvanized iron pipe carrying water with a mean velocity of 6 ft/s.Oil, with ρ= 900 kg/m3and ν= 0.00001 m2/s, flows at 0.2 m3/s through 500 m of 200-mm-diameter cast-iron pipe. Determine (a) the head loss and (b) the pressure drop if the pipe slopes down at 10° in the flow direction.
