ok i have a problem, i did a experiment to find the weir flow. Using q= cd 2/3 b root (2g) x h^(3/2)

I measured b the width of the weir and the height. i was asked to find out the discharge coefficient cd. what i did was add weight to an unknow mass. so the original mass mass flow was x then we added 2.5kg each time. so to find to the flow q i do x (unknow mass) /time. I know have two unknow variables x and cd, where cd isnt constant. so i cant equate two readings. is cd was constant then u could.

2. Relevant equations

q= cd 2/3 b root (2g) x h^(3/2)

3. The attempt at a solution

ive given up
