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...

A Newtonian body wash undergoes steady shear between two horizontal parallel plates. The lower plate is fixed, and the upper plate of 1kg moves with constant velocity of 20 m/s. The distance between the plates is constant at 5 mm. The area of the upper plate in contact with the fluid is 0.5 m2 . a) What is the viscosity of the product and b) the momentum diffusivity if its density is 1010 kg/m3?

A thin flat plate is placed in between two parallel plates (top and bottom) as shown in Figure Q1. The distance separating this thin flat plate with both parallel plates is h. Apart from having a stationary top plate, the thin flat plate is moving at the speed of U and the bottom plate is moving to the left at a velocity of 0.2U. The fluid in the upper flow region (above the thin flat plate) and in the lower...

3 Question 5. (10 pts) Viscosity: Two flat plates are shown in figure on the right. The top plate is located at a distance b above the fixed plate and it is pulled along with constant speed V. The other thin plate is located a distance cb above the fixed plate, where (<e<1. This plate moves with speed V2, which is determined by the viscous shear forces 12 imposed on it by the fluids on its top and bottom. The...

A parallel plate capacitor is made of two square plates of side "l" separated by a distance "d". Each plate lies parallel to the x-z plane. (see picture below) The capacitance of the parallel plate capacitor is Cpp = One of the plates is now tilted at a SMALL angle as shown Note that the separation between the plates, d(z) now varies with "z". Consider this capacitor as an infinite number of parallel plate capacitors connected to each other in...
