Liquid flows horizontally through a circular tube filled with sand grains that are spherical and of the same diameter. As liquid flows through this sand bed, the liquid experiences a pressure drop. The pressure drop Ap is a function of average fluid velocity V, diameter D of the sand grains, spacing S between adjacent grains, liquid density p, and viscosity µ. Use dimensional analysis to determine an expression for the pressure drop in terms of these variables.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Fluid Mechanics

Liquid flows horizontally through a circular tube filled with sand grains that are spherical and of the same
diameter. As liquid flows through this sand bed, the liquid experiences a pressure drop. The pressure
drop Ap is a function of average fluid velocity V, diameter D of the sand grains, spacing S between
adjacent grains, liquid density p, and viscosity µ. Use dimensional analysis to determine an expression
for the pressure drop in terms of these variables.

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.

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.)
