Module $3-$Unsteady Flow in Conduits: Mudule Problem #$6$ Solution

A $50-m$ long by $21-m$ wide rectungular swimming pool is $1,800m$ deep at one end and $3\mathrm{.}500m$ deep at the other end. The depth varies uniformly between the ends. The pool is drained through two $150-mm$ diameter orifices at the deep end of the pool. The coefficrent of discharye for the orifaces is $0,62.$ Determine how long it would take to empty the pool. $(6\mathrm{.}02hr)50m50m$

Civen:

longrightarrow Coefficient of discharge $(Cd)=0\mathrm{.}62$

$$ Aren of orifice $(A_0)=\frac{d^2}{4}=\frac{(0\mathrm{.}15{)}^2}{4}=0\mathrm{.}017671458m^2$

longrightarrow Gravitational constant $(g)=9\mathrm{.}82\frac{m}{s^2}$
