OPEN CHANNEL FLOW EXPERIMENT

Define the experimental work briefly and support your expression with the necessary figures and photographs.

Determine the discharge $($Q$),$ unit width discharge $($q$),$ uniform water depth $($h$),$ mean velocity, specific energy and regime of the flow in the open channel.

Check if the water is able or not to pass through the constriction and hump with its existing specific energy.

Determine the water depth $(cm)$ and velocity $(c\frac{m}{sec})$ with the placement of hump, gate, and constriction into channel.

Determine the minimum specific energy, critical depth and the regime of the flow with the placement of hump, gate, and constriction into channel.

Determine the energy loss in the Hydraulic Jump with the placement of a hump, gate, and constriction into channel.

Experimental Data:

Hump Height :$2\mathrm{.}5cm$

Constriction Cross$-$Section : $10cm**1,25cm$

Open Channel Width $,$:$7,5cm$

Mass $=5kg$ and time $=$ seconds

Water depths with replacement of gate: $y_0=,y_1=,y_2=$

hump $($height$,e=2\mathrm{.}5cm)$: $y_0=,y_1=,y_2=$

constriction: $y_0=y_1=,y_2=$

Formulas:

$E_1=h_1+\frac{v_1^2}{2**(g)}$

$E_{\text{m}\text{i}\text{n}}=\frac{3}{2}{h}_c$

$h_c=\sqrt[3]{\frac{q^2}{g}}$

$E_1{E}_{\text{m}\text{i}\text{n}}+e$

$Q=V**A$

$q=\frac{Q}{B},E=\frac{(h_2-h_1{)}^3}{4**h_2**h_1}$

E $,=$ Specific Energy $[$L$]$

Emin $=$ Minimum Specific Energy $[$L$]$

$h_c,=$ Critical Water Depth $[$L$]$

e $,=$ Hump Height $[$L$]$

Q $,$ Discharge $L^3{T}^{-1}$

$q,=$ Unit Width Discharge $L^3{T}^{-1}{L}^{-1}$

g $=$ Gravity Acceleration $[L^2{T}^{-1}]g=981c\frac{m}{s^2}$
