Using Francis Formula, Compute The Discharge of a Rectangular
Using Francis formula, compute the discharge of a rectangular weir 40 cm long with a head of 10 cm having no end contraction.
Francis formula for Calculation using
Q = 1.84*L*(((Hi+Hf)^1.5)-(Hf^1.5))
Given Data is L = 40 cm, Hi = 10 cm, Hf = 0 cm
Apply data in Francis formula
Q = 1.84*40*(((10+0)^1.5)-(0^1.5))
Q = 23.27 lit/sec
