Chapter 7, Problem 7.5P
Interpretation Introduction

Interpretation:

The average particle size and surface area per unit mass of solid are to be determined for a packed bed.

Concept Introduction:

Pressure drop in a packed bed during laminar flow depends on superficial velocity, particle diameter and void fraction. However, this assumption works only when the Reynolds number is less than unity. The surface area to volume ratio of non-spherical particles is inversely proportional to the particle diameter and sphericity. Finally, volume of particles is defined as the ratio of mass to density of the particles.

Derive an expression for incompressible flow in a horizontal pipe of constant diameter andwithout fittings or valves which shows that the pressure is a linear function of pipe length. Whatother assumptions are required for this result? Is this result valid for non-horizontal pipes? Howwill the presence of fittings, valves and other hardware affect this result?
Ethylene glycol liquid is used as an antifreeze in many applications. If it is stored in a vessel at a pressure of at 150 psig flows through a ¾ inch-diameter hole to atmospheric pressure. Estimate the discharge rate if the ambient pressure is 1 atm. For ethylene glycol at 77°F, the specific gravity is 1.15 and the viscosity is 25 cP. The molecular weight is 62.07.
