Introduction

Practical 11 Hydro Power Simulation                            Samed Nakhla

## Introduction

When water flows from the reservoir (bottle) to the end of the pipe PE is converted to KE, this causes the water to squirt out of the pipe with velocity v falling in the parabolic path shown in the diagram below.

## Theory

Applying the law of conservation of energy to a mass m of water

The water falls with uniform acceleration, applying the equations of uniform acceleration to the vertical motion:

The horizontal velocity of the water is constant therefore:

Substituting for t gives

Substituting into the energy equation gives

## Method

By measuring the height of the top of the water in the bottle and the distance squirted by the water confirm this relationship and find y.

## Results

Conclusion

After all, the practical is done with some errors and mistakes that are clear in the graph, and I think this graph can be made a lot better if we use the suggestions above or similar ones.

This student written piece of work is one of many that can be found in our International Baccalaureate Physics section.
