A 1/4” inside diameter pipe is used to transport SAE 30 motor oil (µ = 0.006266 slug/ft-s and ρ =1.7267 slug/ft3) over a distance of 100 ft. Assuming that the pipe is horizontal and the flow throughit is steady, laminar, and fully-developed, what gauge pressure must a pump develop at the head ofthe pipe to provide a flow rate of sufficient to fill a quart bottle every 5 seconds? [6291 psi] Whatis the Reynolds number (based on diameter) for this flow? [112.5] Is the assumption of laminar flowreasonable?
The flow rate of water in a garden hose is measured using the bucket-andstopwatch method. Filling a 5-L bucket takes 75 seconds. If the inner diameter of the hose is 10 mm and the density and viscosity of water are approximately 998 kg m-3 and 0.9 cP, respectively, (a) is the flow inside the hose laminar or turbulent? (b) If the flow rate is adjusted such that the flow is with Re = 2100, how long would it take to fill the same bucket?

A petroleum product of viscosity 0.5 m Ns/m2 and density 700 kg/m3 is pumped througha pipe of 0.15 m diameter to storage tanks situated 100 m away. The pressure drop alongthe pipe is 70 kN/m2. The pipeline has to be repaired and it is necessary to pump the liquid by an alternative route consisting of 70 m of 200 mm pipe followed by 50 m of 100 mm pipe.
