Discussion $[15$ marks$]$

Discuss results obtained in Table $1,$ table $2,$ table $3$ and table $4$ in four separate paragraphs and discuss what you think about the findings. When discussing each paragraph, remember to include $-$

anything you found interesting

descriptions of readings in gage A and $B$ with reasoning

justification if the reducing valve was doing its job. charts$/$graphic elements to score more marks

Conclusion & Recommendation $[10$ marks$]$

Did we have any load in our circuit? Support your answer with proof. Explain, how load affects the circuit.

How does pump react to the load?

How did the reducing valve perform its job?

Where did you see the self$-$relieving feature of the PRV in effect? Explain briefly.

How do you explain the pressure at gage B in table$-1$ when the needle was completely closed?

Write a few recommendations $($Do not write anything general! Write from your experience! There will be no marks for vague recommendations.$)$

Real life Application $[7$ marks$]$

Provide one example with a picture and give rationale how it uses the same hydraulic principle as the experiment.
