The laminar flow of a permanent incompressible Newtonian fluid in a long cylindrical pipe with a diameter D in vertical position is considered. Gravitational effects are taken into account, flow is carried out with a constant pressure gradient and gravity effect in the z- direction. a. Express the problem on the figure, write the given and accepted. b. Find the velocity profile in the fluid. c. Develop the relations that express the volumetric flow and shear stress in the pipe...

4. An incompressible fluid with viscosity u and density p was contained in pipe of length L and radius R. Initially the fluid is in rest. At t=0, a pressure difference of AP is applied across the pipe length which induces the fluid flow in axial direction (V2) Only varies with time (t) and pipe radius (r). There is no effect of gravity. To describe the fluid flow characteristics, after the pressure gradient is applied, answer the following questions: a)...

Step by step solution please
A 16-inch gasoline pipe line is transport gasoline at a flow rate of 200 gallon per minute. Please calculate how much pressure gradient dp/dx is needed, using the N-S equation provided in below? (Hint: Assuming the flow in the pipe line is laminar so you can use the Poisson flow to solve the problem. Dynamic viscosity of gasoline is 0.0006 N/m*2 second; density of gasoline is 0.77 kg/L.) Cylindrical coordinates (r.0,2) We consider an incompressible,...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

The figure below is a section of a conducting rod of radius R1=1.30mm and length L=11.00mm inside a thick-walled coaxial conducting cylindrical shell of radius R2=10.0R1 and the (same) length L. The net charge on the rod is Q1=-4.30∗10−12C that on the shell is Q2=-4.00Q1. a) What is the magnitude E of the electric field at a radial distance of r = 2.50R2? b) What is the direction of the electric field at the radial distance (inward, outward, or zero)?
