Water with depth $y_1$ flows over a BCW $($water height $=y_2$; weir height $P).$

Directly downstream of the weir, the channel bottom rises by an amount $d$ above

the original channel bottom and the water depth is $y_3.$ Further downstream, a

hydraulic jump occurs where the water depth becomes $y_4.$

If $y_1=2y_2$ and $F_3=2,$ find:

a$)F_1$

b$)\frac{y_3}{y_1}$

c$)\frac{d}{v_1}$

d$)\frac{y_4}{y_1}$

e$)\frac{P}{y_1}$
