# Labratories

These two laboratory sessions examine how well the theoretical analysis of fluid dynamics describes what we observe in practice.

During the laboratory you will take measurements and draw various graphs according to the details on the laboratory sheets. These graphs can be compared with those obtained from theoretical analysis.

You will be expected to draw conclusions as to the validity of the theory based on the results you have obtained and the experimental procedure.

After you have completed the two laboratories you should have obtained a greater understanding as to how the theory relates to practice, what parameters are important in analysis of fluid and where theoretical predictions and experimental measurements may differ.

The two laboratories sessions are:

**Impact of jets**on various shaped surfaces - a jet of water is fired at a target and is deflected in various directions. This is an example of the application of the momentum equation.

**The rectangular weir**- the weir is used as a flow measuring device. Its accuracy is investigated. This is an example of how the Bernoulli (energy) equation is applied to analyses fluid flow.

**compulsory**course-work. You must attend them. Should you fail to attend either one you will be asked to complete some extra work. This will involved a detailed report and further questions. The simplest strategy is to do the lab.]
