The value of $r$ for the pipe $AB$ is $1$ and for the pipe $BC$ is $2$. If the ... is equally divided between the pipes $AB$ and $AC$, the value of $r$ (up to two decimal places) for the pipe $AC$ should be _______

Two reservoirs are connected through a $930$ m long, $0.3$ m diameter pipe, which has a gate valve. The pipe entrance is sharp (loss coefficient $=0.5$) and the valve is half-open (loss coefficient $=5.5$). The head difference between the two reservoirs is $20$ m. ... $0.03$ and $g=10\:m/s^2$. The discharge in the pipe accounting for all minor and major losses is ___________ $m^3/s$.

A hydraulic jump takes place in a frictionless rectangular channel. The pre-jump depth is $y_p$. The alternate and sequent depths corresponding to $y_p$ are $y_a$ and $y_s$ respectively. The correct relationship among $y_p, \: y_a$ and $y_s$ is: $y_a < y_s < y_p$ $y_p < y_s < y_a$ $y_p < y_s = y_a$ $y_p = y_s = y_a$
