water flow venturi meter problem! Heeeelp please :)
Hi,
The objects of my experiment where
1) to find out the theoretical and experimental pressures in a venturi tube,
2) To determin the coefficient of discharge for the venturi
here is the data i collectec http://cniles0.tripod.com/work020.jpg
im having problems with my two objectives,
i have i have been playing arround with the following formula's but with no luck,
.
m = A2 [sqrt (2 x delta p x viscosity)/1-k^2
K=A1/A2
therefore K = 2.63998
.
V = 201.1 x sqrt [2 x delta p x 1 (waters viscosity coeffient)]/[1 - 2.64^2]
Here is the hand out i got, giving some formula's and it gives cross sectional values for the venturi tube but not sure what do do with these?

i have worked out the experimental rh but i don't know how to find out the therotical rh, and I am not sure what Cb (show on results table is).
thanks for any help ppl
