Chapter 1, Problem 1.5P

(a)

Interpretation Introduction

Interpretation:

The volumetric flowrate of the entering gas being treated is to be calculated.

Concept Introduction:

The formula to calculate the volumetric flowrate $\left(\dot{V}\right)$ of a fluid from the velocity $\left(v\right)$ of the fluid is:

  $\dot{V}=Av$ ...... (1)

Here, $A$ is the cross-sectional area of the pipe or column through which the fluid id flowing.

(b)

Interpretation Introduction

Interpretation:

The amount of ammonia being absorbed is to be calculated.

Concept Introduction:

The formula to calculate the volumetric flowrate $\left(\dot{V}\right)$ of a fluid from the velocity $\left(v\right)$ of the fluid is:

  $\dot{V}=Av$ ...... (1)

Here, $A$ is the cross-sectional area of the pipe or column through which the fluid id flowing.

In a system, a conserved quantity (total mass, the mass of a particular species, energy or momentum) is balanced and can be written as:

  $input+generation-output-consumpumtion=accumulation$

Here, ‘input’ is the stream which enters the system. ‘generation’ is the term used for the quantity that is produced within the system. ‘output’ is the stream which leaves the system. ‘consumption’ is the term used for the quantity that is consumed within the system. ‘accumulation’ is used for the quantity which is built up within the system.

All the equations which are formed are then solved simultaneously to calculate the values of the unknown variables.

An ideal gas is a gas that obeys ideal gas laws which is a simplified equation of states.

A real gas behaves as an ideal gas at a higher temperature and lower pressure. At STP, 1 lbmol of an ideal gas has a volume of $359{\text{ ft}}^3$ and the temperature is taken in the Rankine scale.
