An incompressible liquid with negligible viscosity and density ρ = 1.75 slug/ft3 flows steadily through a horizontal pipe. The pipe cross-section area linearly varies from 15 in.2 to 2.5 in.2 over a length of 10 feet. Develop an expression for and plot the pressure gradient and pressure versus position along the pipe, if the inlet centreline velocity is 5 ft/s and inlet pressure is 35 psi. What is the exit pressure? Hint: Use relation

- The laminar flow of a fluid with viscosity µ and density ρ in a circular pipe of radius R has a velocity distribution described by where UCL is the velocity on the centerline where r = 0. (a) Using a control volume analysis, find τw, the shear stress at the wall, in terms of R and the pressure gradient dp/dx. (b) Using the expression for the velocity profile, find τw, the shear stress at the wall, in terms of µ, R, and UCL. (c) Find the average velocity in terms of UCL. (d) Using the results from parts (a)-(c), show that where Re is the Reynolds number based on the diameter D.arrow_forwardThe Reynolds number, pVD/μ is a very important parameter in fluid mechanics. Determine its value for ethyl alcohol flowing at a velocity of 2 m/s through a 2-in.- diameter pipe. Re=arrow_forwardYour team is designing a chemical processing plant. You are the liquid handling and transportation specialist, and you need to transport a solvent (μ = 3.1 cP, ρ = 122k kg/m3) from a storage tank to a reaction vessel. Due to other equipment constraints, the fluid velocity must be 0.8 m/sec, and you must use stainless steel piping (ε = 0.00015 mm) with a total length (L) of 12 m. Determine the pipe inner diameter (ID) you will need to achieve a pressure drop of 0.3 kPa. Use the Moody chart.arrow_forward

Explain briefly what is meant by fully developed laminar flow. The velocity u at any radius r in fully developed laminar flow through a straight horizontal pipe of internal radius ro is given by u= (1/4µ)(ro2-r2)dp/dx dp/dx is the pressure gradient in the direction of flow and u is the dynamic viscosity. Show that the pressure drop over a length L is given by the following formula. Ap=32μLu/D² The wall skin friction coefficient is defined as C = 21/(pum²). Show that C= 16/Re where Re = pumD/μ and p is the density, um is the mean velocity and to is the wall shear stress.arrow_forward
- Help me plsarrow_forwardliquid (density 800kg/m3, viscosity 10−3 kg/ms) has to be supplied at a mean speed of 2m/s through a pipe of diameter 12.5mm with a surface roughness equivalent to that for structural steel. What is the magnitude of the pressure gradient necessary to achieve this flow? Your answer should have a positive sign and be to the nearest 10 Pa/m. You may wish to use the Moody diagram.arrow_forwardA2 A Newtonian fluid with viscosity (Mu) flows upward at a steady rate between two parallel plates that make an angle y with the horizontal. The fluid thickness h is much smaller than the width of the channel W. The pressures at each end, P(0) and P(L), are known and the pressure variations in the y-direction are small. Assume that Vy and Vz = 0 and Vx is a function of y alone. Use the shell balance to approach : - the Total flowrate, QVarrow_forward
