Oil, with a vapor pressure of 20 kPa, is delivered througha pipeline by equally spaced pumps, each of which increases the oilpressure by 1.3 MPa. Friction losses in thepipe are 150 Pa per meter of pipe. What is the maximumpossible pump spacing to avoid cavitation of the oil?
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?
A necked-down section in a pipe flow, called a venturi,develops a low throat pressure that can aspirate fluidupward from a reservoir, as in Fig. UsingBernoulli’s equation with no losses, derive an expressionfor the velocity V 1 that is just sufficient to bring the reservoirfl uid into the throat.
Water flows at 20°C through a new cast iron pipe at a velocity of 4.2 m/s. The pipe is 400 m long and hasa diameter of 150 mm. Determine the head loss due to friction.

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. If the existing pump is capable of developing a pressure of 300 kN/m2, will it be suitable for use during the period required for the repairs? Calculate the pressure drop for the alternative pipe system. Take the roughnessof the pipe surface as 0.05 m
