Chapter 5, Problem 5.6P

Interpretation Introduction

(a)

Interpretation:

An expression for the transducer reading should be derived.

Concept introduction:

Pressure of a liquid open to atmosphere can be written as,

$P=P_{atm}+h\rho g$

Where, P_atm is the atmospheric pressure, h is height of the liquid column and ? is density of liquid

Interpretation Introduction

(b)

Interpretation:

The given expression should be validated.

Concept introduction:

Pressure of a liquid open to atmosphere can be written as,

$P=P_{atm}+h\rho g$

Where, P_atm is the atmospheric pressure, h = height of the liquid column and ? = density of liquid

In addition, the equation can be validated by checking the units.

Interpretation Introduction

(c)

Interpretation:

The following variables should be calculated.

1. ${\rho }_{sl}$
2. $x_c$
3. The total slurry volume
4. The mass of crystals in the slurry
5. The mass of anhydrous copper sulfate
6. Mass of liquid solution
7. The volume of liquid solution

Concept introduction:

Pressure of a liquid open to atmosphere can be written as,
