Ve A river bed is covered with a layer of small stones as shown in the figure. The diameters of stones vary between 3.7 mm and 3.7 cm. It is observed that at some critical flow velocity some stones will rise and be transported along the river. A model is to be used to determine this critical velocity. Assume that the river bed is horizontal and the critical velocity, Ve, is a function of the particle diameter, d, the fluid density, p, and viscosity, u, the density of the particles, Pp, and the acceleration of gravity, g. a) Determine a suitable set of dimensionless variables for this problem and clearly mark them on your solution sheet. How many pi terms are required to describe the problem?

The Reynolds transport theorem (RTT) is discussed in Chap. 4 of your textbook. For the general case of a moving and/or deforming control volume, we write the RTT as follows: d pb dV + pbV-ñ dA dt dt dB sys where Vr is the relative velocity, i.e., the velocity of the fluid relative to the control surface. Write the primary dimensions of each additive term in the equation and verify that the equation is dimensionally homogeneous. Show all your work. (Hint: Since B can be any property of the flow-scalar, vector, or even tensor—it can have a variety of dimensions. So, just let the dimensions of B be those of B itself, {B}. Also, b is defined as B per unit mass.)

A liquid of density ? and viscosity ? flows by gravity through a hole of diameter d in the bottom of a tank of diameter DFig. . At the start of the experiment, the liquid surface is at height h above the bottom of the tank, as sketched. The liquid exits the tank as a jet with average velocity V straight down as also sketched. Using dimensional analysis, generate a dimensionless relationship for V as a function of the other parameters in the problem. Identify any established nondimensional parameters that appear in your result. (Hint: There are three length scales in this problem. For consistency, choose h as your length scale.) except for a different dependent parameter, namely, the time required to empty the tank tempty. Generate a dimensionless relationship for tempty as a function of the following independent parameters: hole diameter d, tank diameter D, density ? , viscosity ? , initial liquid surface height h, and gravitational acceleration g.
A laboratory study models the flow around the pier of an off-shore wind turbine with a scaled model of Lr = 20. Determine the model velocity (VM) past the pier, if the water travels with V = 2.2 km/h past the prototype pier. You can assume that water with the same fluid properties is used in both model and prototype with density of Pw = 1005 kg/m³ and dynamic viscosity of nw = 0.001 Pas. HINT: the flow around the pier is described by the Reynolds number. VM m/s (Provide your answer to 3 decimal places)
