Fluid Mechanics Laboratory question - Help needed ASAP
Â
I recently did a Fluid Mechanics laboratory and I'm having trouble with 5 questions in particular.
Â
The questions are mostly related to plotting experimental data and constructing pump curves.
Â
Please use Microsoft Word and Excel.
Â
I have attached my laboratory results, the instructions of the lab and the questions I need help with (highlighted in red).
Â
Just in case, I will write down the questions below;
Â
2. For each setting, plot the experimental data of hp versus Q for the centrifugal pump (where hp is in m and Q is in L/min)
Â
3. Construct the pump curves by generating, for each setting, a curve of best fit to the experimental data in the form ofhp = a + bQ^c where hp is in m and Q is in L/min. Add these curves to the plot in Question 2 and report the values of a, b and c for each pump setting.
Â
5. What are the implications of having the throttling valve prior to the pump inlet? Explain in terms of NPSH.
Â
6. Using reasonable estimates of friction factors (for a smooth pipe) and minor loss coefficients, construct a curve of theoretical system head for the case of the valve being fully open.
Â
7. For the 3 experimental runs with the valve fully open, how do your estimates of system head loss compare to the experimentally-obtained values?
Â
Please make sure you can answer the questions correctly before attempting to answer.

Thanks in advance
