the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give ...

Comparing Equation 2 with Equation 1 provides insight into the relationships of the parameters in Manning’s equation. V avg = 10.3972 x (gS/α) 1/2 x R 3/8 = (1.486/n) x R 2/3 x S 1/2 ...

Continuity Equation When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of ...
