Chapter 7, Problem 7.4P
Interpretation Introduction

(a)

Interpretation:

The air emission and energy consumption per 1000 paper sacks used and per 2000 plastic sacks used are to be calculated.

Concept introduction:

Air emission is the measure of the amount of pollutants released in the air during any process. These air pollutants can damage the quality of air. Energy consumption is the amount of energy used during a process.

Interpretation Introduction

(b)

Interpretation:

The air emission and energy consumption per 1000 paper sacks used and per 2000 plastic sacks used, with an assumption that the used sacks are recycled by 60%, are to be calculated. The percentages by which air emission and energy consumption are reduced for each sack material, as a consequence of the recycling process, is to be calculated.

Concept introduction:

Air emission is the measure of the amount of pollutants released in the air during any process. These air pollutants can damage the quality of air. Energy consumption is the amount of energy used during a process.

Interpretation Introduction

(c)

Interpretation:

The number of grocery sacks used in a day in the United States is to be estimated. The average rate of energy consumption associated with the production, use, and disposal of these sacks is to be calculated. The amount of MW saved by 60% recycling process is to be calculated.

Concept introduction:

Air emission is the measure of the amount of pollutants released in the air during any process. These air pollutants can damage the quality of air. Energy consumption is the amount of energy used during a process.

Interpretation Introduction

(d)

Interpretation:

The important factors that were not taken into account in making the given decision, including considerations of the potential environmental impact of each type of bag is to be stated.

Concept introduction:

Air emission is the measure of the amount of pollutants released in the air during any process. These air pollutants can damage the quality of air. Energy consumption is the amount of energy used during a process.

Q1/obtain the transfer function for the block diagram shown in the figure below: G4 G
(Population density parameters from sieve analysis data)2 One hundred fifty grams of crystals separated from one litre of suspension from an MSMPR crystallizer is subjected to screen analysis to get the following data: Tyler mesh Mass(g) 12/14 28.5 14/20 29.2 20/28 28/35 35/48 below 48 mesh 37.5 27 24.7 3.1 Mesh no./ screen opening(um) data: 12/1410 μm; 14/1190; 20/841; 28/595; 35/420; 48/297. The working volume of the crystallizer is 200 litres, and the rate of withdrawal of the slurry is 250 litre per hour. Given pc = 1400 kg/m³ and volume shape factor o, = 0.42, determine the crystal growth rate and the zero-size population density of the crystals. What is the rate of nucleation, Bº?
