Question

Calculate coefficient of discharge and Q for a recangular and triangular (90 Degrees) wier with the provided data including flow rate into the holding tank, and height of the water surface as it flows over the weir for each flow rate. Equations Provided.

(This the only data I was told to record, and Im entirely lost on how to do this)
