## Homework Statement

a gemoetrical similar open chanel model is constructed with 10: 1 , if the model discharged 7m^3 /s , what is the corresponding discharge in prototype?

## Homework Equations

## The Attempt at a Solution

Q = (L^3) / T ,

[ (Lp^3)/ (Tp) ] / [ (Lm^3) / Tm ] = (Lr^3) / Tr

[/B]

but , i assume (Lr^3 ) = (

but , i assume (Lr^3 ) = (

**Lp^3) / (****Lm^3)**

so , Qp = (5^3) x 7 = 875 m^3 /s , is it correct ?

or it should be (1/125 ) x 7 = 7/725

so , Qp = (5^3) x 7 = 875 m^3 /s , is it correct ?

or it should be (1/125 ) x 7 = 7/725
