Froude Number, Flow velocity, Acceleration of gravity,Calculations
and mean depth calculation formula and examples

I want to Calculate
Froude Number(Fn)
Flow Velocity(Fv)
Acceleration of Gravity (Ag)
Mean depth (Md)

[insert_php] echo $display;[/insert_php]

[insert_php]

if($A==4)
{
$display= “Froude Number(Fn) = “;
echo “

Result of what you enter is : FroudeNumber =

“;
echo “Formula : Flow velocity / (sqrt(Acceleration of Gravity * Mean depth))
“;
echo “Result = “.$Fv.”/(sqrt”.$Ag.”*”.$Md.”))
“;
echo “Result = “.$result.”

“;

}

elseif ($A==1)
{
$display = “Flow velocity(Fv) =”;

echo “Calculate Flow Velocity
“;
echo “Formula : Froude Number * (sqrt(Acceleration of Gravity * Mean depth))
“;
echo “Result = “.$Fn.”* (sqrt(“.$Ag.”*”.$Md.”))

“;

}

elseif($A==2)

echo “Calculate Acceleration of Gravity
“;
echo “Formula : (Flow Velocity ^ 2) * (Mean depth * (Froude Number ^ 2))
