Problem 5. Use a kinematic viscosity of 1.41 x 10-5 ft2/s or 1.307 x 10-6 m2/s and the Moody Diagram for the following. dt bus 9d 9d blow terw 9dt i a. For a relative roughness of 0.0001, what would be the minimum Reynolds number resulting in fully turbulent flow. If the flow velocity were 5.0 ft/s, what minimum diameter would be required? b. The head loss in a section of 200-mm-diameter pipe (k = 0.090 mm) was calculated assuming fully turbulent flow. If the resulting flow rate is 72 liters per second, would the friction factor need to be adjusted? If so, what would be the new f? c. A 4-in-diameter pipe is assumed to be smooth. A test showed a head loss of 1.08 ft in 100 ft of pipe when the flow was 0.304 cfs. Is the assumption correct? d. A 1/4-in-diameter copper pipe has a flow of 0.150 gpm. What would be the friction factor for this flow?
