Question 4 A 150 mm diameter pipe is connected to a large tank with a bellmouth inlet. The pipe is carrying oil (specific gravity 0.85) with an absolute viscosity of 0.0056 N-s/m² and the roughness elements of the pipe wall is estimated as k = 0.9 mm. (a) Above what flow rate will this pipe behave as a fully rough pipe? (b) Below what flow rate will it behave as a smooth pipe?

choose the correct multiple-choice answer and also show your work): The Darcy friction factor in Branch b in the figure below is 0.025 and the turbulent friction factor in Branch b is 0.021. If this 0.1342-ft ID pipe is 16ft long, determine the head loss in Branch b in terms of ??2.The elbows are 90°long radius. Neglect losses in the junctions.

Compute the head loss (in meters) in 2000 m of horizontal, steel pipe with nominal pipe size of 300 mm and SCH 30. The pipe is carrying water with an average velocity of 1.88 m/s. Take water at 20°C to have a viscosity of 1.00E-3 Pa-s and density of 1000 kg/(m^3). Take the roughness of steel pipe to be 0.048 mm.   Round your answer to 2 decimal places.
