Into a bakery dough mixing chamber water enters at the rate of 200L/s through pipe A. Cooking oil with specific gravity 0.80 is forced in at 50L/ through pipe B. Assuming the liquids are incompressible and form a homogenous mixture of oil globules in water. Evaluate the average velocity of the mixture leaving through a pipe C of diameter 300mm in m/s.
1. A given pipe first carries water and then carries air at 15°C and atmospheric pressure. What is the ratio of the mass discharge rates and the volume discharge rates, if the friction factors were the same for these two flows? 2. Two horizontal pipes of the same length and relative roughness carry air and water, respectively, at 60°F. The velocities are such that the Reynolds numbers and pressure drops for each pipe are the same. Find the ratio of the average air velocity to water velocity.
Question 4: Consider laminar flow through a very long straight section of round pipe. It is shown that the velocity profile through a cross-sectional area of the pipe is parabolic, with the axial velocity component given by V=2V av (1 R²) avg where R is the radius of the inner wall of the pipe and Vavg is the average velocity. Calculate the momentum-flux correction factor through a cross section of the pipe for the case in which the pipe flow represents an outlet of the control volume, as sketched in side Figure. CV R Vave
The present pumping rate of crude oil through the Alaska Pipeline with an ID of 39 in is 550,000 barrels per day (1 barrel is 42 U. S. gallons). For crude oil at 60ºC, take ρ = 860 kg/m3 and μ ≈ 0.004 kg/m·s. What would be the maximum rate if the flow were constrained to be laminar? Take π = 22/7. Answer is asking for maximum flow rate for barrels per day

Water from a reservoir is pumped over a hill through a pipe 3 ft. in diameter, and a pressure of 35 psi is maintained at the summit, where the pipe is 300 ft above the reservoir. The quantity pumped is 55 cfs, and by reason of friction in the pump pipe there is 10 ft of head loss between the reservoir and the summit. What amount of energy must be furnished the water by the pump in kilowatts?

Question A liquid flows through the horizontal pipe of varying cross section. Calculate the areas of the larger and smaller cross sections by measuring their diameters. Measure the speeds of the liquid in both larger and smaller cross sections. Calculate the liquid rates of flow in both sections. Calculate the ratio of the rates of flow.
