Section 2 Introduction

 

Generating electricity using stored water provides energy to millions of people. The amount of water flowing through the turbines helps determine how much electricity is produced. The rate at which water is used has to be controlled, or there is a chance the storage area will be emptied.

 

In this section you will look at rates of change and ways to calculate these rates. You will use proportional reasoning and unit analysis, and you will use both methods together. With these methods you will be able to solve problems in either the imperial or the SI measurement system. You will see that there are often safety issues associated with slopes and rates of change.
