Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates (Figure \(3(a))\). The top plate is moving at speed \(V\), and the bottom plate is stationary. The distance between these two plates is \(h .\) The gravity acts in the \(z\) direction so the flow can be considered essentially two dimensional in \(x-y\) plane. Assume there acts an applied pressure gradient in the \(x\) -direction with its gradient given by, \(\partial P...

Couette Flow: flow between 2 long concentric cylinders of radii Ro and Ri, created by the rotation of one of them. Solve the flow problem for a Newtonian, incompressible fluid for the following two cases: 1. The outer cylinder of radius Ro is rotating with an angular velocity Ω (s^-1 for units). Also calculate the torque for this. 2. The inner cylinder of radius Ri is rotating with an angular velocity -Ω (s^-1 for units). Also calculate the torque for...

The velocity profile for a steady laminar flow in a circular pipe of radius R is given by u=u0(1−r2R2) . If the fluid density varies with radial distance r from the centerline as ρ=ρ0(1+rR)14 , where ρ0 is the fluid density at the pipe center, obtain and choose the correct relation for the bulk fluid density in the tube.

Consider the steady flow between two flat plates. The plates are 10 cm apart and the width of the channel is 10 cm. Water is the working fluid. The flow velocity varies linearly from zero at the bottom plate to 10 m/s at the top plate. (This general class of flows is known as Couette Flow). Determine the total mass flow and momentum per unit time crossing an imaginary plane across the channel.

Two streams are mixed to form a single stream. Only the steady flow in the mixed stream is known. A soluble salt is added to one of the original streams at a steady state and samples show the stream to have a 4.76% salt content by weight. Samples of the combined stream show it to be 0.62% salt content by weight. What is the flow rate of the two original streams ?

Consider the two-dimensional laminar boundary layer flow of air over a wide 15 cm long flat plate whose surface temperature varies linearly from 20°C at the leading edge to 40°C at the trailing edge. This plate is placed in an airstream with a velocity of 2 m/s and a temperature of 10°C. Numerically determine how the surface heat flux varies along the plate. Explain the results obtained with proper reasoning. Support your results with scaling analysis wherever possible.I need c++...
