Appendices: 1) Raw data. 2) Data analysis and sample of calculation. 3) Two plot for orifice and venturi tubes. Data Analysis: a) Pitot tube : from the data I got, Q (m3/s) in table 1 calculated by dividing the volume over the time. Then, V(exp) calculated by dividing Q(exp) over the cross-sectional area. Next, the pressure drop was calculated by multiplying the height difference by the gravity constant by the density. Then, (V)the was calculated by eq1. Also, the Reynolds was calculated by multiplying the diameter by the velocity by the

Unformatted text preview: diameter then divided over the viscosity. b) Orifice tube : Q was measured experimentally by dividing the volume over the time. Then, the pressure drop was calculated same as in the Pitot tube. Next, the cross section area for the orifice was calculated (A0). Then,(Q)the was calculated by eq2 and eq3. c) Venturi : the procedure f calculation same as in the orifice by using eq4 and eq5. d) The discharge coefficient was found from plot which is the slope for each plot of orifice and venturi....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
