Fluid Mechanics Laboratory question - Help needed ASAP
I recently did a Fluid Mechanics laboratory and I'm having trouble with 5 questions in particular.
The questions are mostly related to plotting experimental data and constructing pump curves.
Please use Microsoft Word and Excel.
I have attached my laboratory results, the instructions of the lab and the questions I need help with (highlighted in red).
Just in case, I will write down the questions below;
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)
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.
5. What are the implications of having the throttling valve prior to the pump inlet? Explain in terms of NPSH.
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.
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?
Please make sure you can answer the questions correctly before attempting to answer.
Thanks in advance
