Q$3.$SOLVE USING HAND $($a$)$ Assume $a=1m,b=4m,$ and the flow to be frictionless in the siphon. Find the rate of discharge in $\frac{m^3}{s}$ and the the pressure head at B if the pipe has a uniform diameter of $150-mm.$

$($b$)$ Oil with an absolute viscosity of $0\mathrm{.}125N.\frac{s}{m^2}$ and a density of $890k\frac{g}{m^3}$ is flowing in a $16\mathrm{.}5cm$ diameter pipe at a $7\mathrm{.}5\frac{L}{s}$ flow rate. The fully developed flow is expected to start after $q,m$ of pipe entrance.

$($c$)$ For the system of pipes in series shown, given that:

The kinematic viscosity is $v=1\mathrm{.}139{10}^{-6}\frac{m^2}{s}.$

The minor losses can be neglected Compute the value of $\frac{?}{\text{b}\text{a}\text{r}}(h)$ for a flow of $750\frac{l}{s}.$
