Cuyamaca College Fluid Mechanics Lab

I have the instructions on the pdf lab, and these below questions are the Homework questions that go at the end of the lab report. On the Lab Manual, when solving for A0, the x used in the equation is actually Pie.

Question 1. Referring to Lecture Notes, why we do not apply the Bernouli equation by
setting level N at the opening of the orifice?

Question 2. Are any of your three CD values close to the accepted value? Which of your three
CD values do you consider the most accurate? Why?

Question 3. In the absence of head loss, what will be the value of (a) Cu and (b) CC ? Use data
from rum No. 1.

Question 4. The overflow pipe was only available for the high h0 runs. How could this have
affected the decreasing h0 runs?

Question 5. Was the maximum scatter of your Q vs. h0 curve within graphic accuracy? If not,
give a logical explanation.
