# Math Help - Calculation for Q = CdA √2GH – find H

1. ## Calculation for Q = CdA √2GH – find H

Hi Guys, I have this calculation I need to find H. – Rephrased question!
Q = CdA √2GH
Q= 163.5 m3/h
Cd = 0.5
A = ∏D2/4 = (∏ x 235.4²)/4 = 43632.39
I need to find the Hight...

So i got:
163.5m³h = 0.5* (πD2/4) √(2 x 9.8 x H)

If your equation is $\displaystyle Q= CdA\sqrt{2}GH$
Then $\displaystyle H = \frac{Q}{ CdA\sqrt{2}G}$
