Blood is carefully fed into two flat plates (which can be considered infinite wrt to the distance between the two plates) placed closely together.
As gravity drives blood flow through the gap between the plates (with thickness ‘L’), we use a microscope to measure the velocity of red blood cells at the location where the flow is at a maximum. Assume that the flow has reached steady state at the point of observation. Based on this setup, derive an equation that will predict the viscosity of blood.
Calculate the viscosity of blood assuming that the distance between the plates is 1 mm, the density of blood is 1000 kg/m3, and the peak velocity of the blood is 40 cm/s.

Two immiscible Newtonian fluids are contained between infinite parallel plates. The plates are separated by distance 4h, and the top fluid layer thickness is h. The bottom layer has thickness 3h. The viscosity of the bottom fluid is three times that of the top fluid. If the lower plate moves at a constant speed of 20 m/s and the upper plate moves at a constant speed of 40 m/s, what is the average velocity within the bottom liquid layer? We...
Consider steady, incompressible, laminar flow of a Newtonian fluid in the narrow gap between two infinite parallel plates. The top plate is moving at speed V, and the bottom plate is moving in the opposite direction at speed V. The distance between these two plates is h, and gravity acts in the negative z-direction. There is no applied pressure other than hydrostatic pressure due to gravity. Calculate the velocity and estimate the shear stress acting on the bottom plate Moving...
2.22. Three parallel flat plates are separated by two fluids. Plate 1 (on the bottom) is at rest. Water, viscosity 0.8007 CP at 30°C, lies between plates 1 and 2. Toluene, viscosity 0.5179 cP at 30°C, lies between plates 2 and 3. The distance between each pair of plates is 10 cm. Plate 3 moves at 3 ms. Find: (a) the velocity of plate 2 at steady-state (b) the force per unit area on plate 3 required to maintain the...
Consider a Couette flow between two flat plates: One plate is stationary, while the other plate is moving with a velocity vo; the distance between the plates is h. Realize that the density and the viscosity of the fluid are roughly constant. You may also presume that the velocity is mostly unidirectional, solely varying in its perpendicular direction. In turn, formulate and solve the differential equation which governs the velocity profile!

Two horizontal plates with infinite length and width are separated by a distance H in the zdirection. The bottom plate is moving at a velocity vx=U. The incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. Align gravity with positive z. Assume that the flow is fully-developed and laminar. If the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. Sketch your system. 2....
