Liquid is flowing through a circular pipe in a laminar phase. Now, the fluid through the pipe is replace with a more viscous fluid and passed through the pipe again with the same velocity. What will be the nature of flow of the fluid? Eddies will star to form B The flow will become turbulent Insufficient data to define The fluid will remain laminar The flow will start to be transitional

Several different classifications of fluid flows were outlined - match each of the class pairs listed. Viscous A. Inviscid Extrernal B. Turbulent Incompressible C. Internal Laminar D. Compressible

2C.4 Falling-cylinder viscometer (see Fig. 2C.4). A falling-cylinder viscometer consists of a long vertical cylindrical container (radius R), capped at both ends, with a solid cylindrical slug (ra- dius KR). The slug is equipped with fins so that its axis is coincident with that of the tube. One can observe the rate of descent of the slug in the cylindrical container when the lat- ter is filled with fluid. Find an equation that gives the viscosity of the fluid in terms of the ter- minal velocity of the slug and the various geometric quantities shown in the figure. Cylindrical slug descends- with speed t -XR- Cylindrical container filled with fluid Fig. 2C.4 A falling-cylinder viscom- eter with a tightly fitting solid cylin- der moving vertically. The cylinder is usually equipped with fins to maintain centering within the tube. The fluid completely fills the tube, and the top and bottom are closed.

Consider an incompressible 2D flow with stream function Y = xy + y³. Determine (a) the velocity at point (3,5). (b) the flow rate per depth for a curved segment y + x² = 4 in the second quadrant.

1) Consider the infinitely tall, annular mixing tank. The fluid to be mixed is Fluid between the inner cylinder and the outer wall. The fluid is mixed by a Fluid spinning the inner cylinder at an angular velocity of n (s-1). The tank has an inner radius of R (m) and the R. inner cylinder has a diameter of k (m). Fluid There is no net flow in the vertical or radial directions. Top view Answer the following questions about Side view this sytem:

2. Adjacent Flow of Two Immiscible Power Law Fluids Two immiscible fluids are contained in the space between two infinite parallel plates. The upper plate, at y = h, is in motion with a velocity U. Initially there is no pressure gradient in the x-direction. We have already solved for the velocity profile between the two plates for a number of different conditions, now we are going to make fluid II non-Newtonian. U Fluid II Interface Between Two Immiscible Fluids ah Fluid I d) Go back to your old assignment (b), but now let's let Fluid II be non-Newtonian. Specifically, model the fluid as a power law fluid with n =ky". Solve for the velocity profile across the channel and sketch the result for a shear thinning and shear thickening fluid as the velocity on the top plate is systematically increased. e) Now remove the velocity of the top plate and instead apply a pressure gradient. What is the velocity profile look like now?

A Newtonian fluid with constant density flows in a parallel-plate apparatus that separated by a distance d and length L as shown in Figure 1. The top plate is moving in z-direction with a velocity uw. Derive the velocity distribution of the fluid, vz as a function of y using equation of motion in Appendix 1. List the postulates and you may neglect the gravity force.
