Interpretation:
The flow rate and pressure head at a point across a siphon is to be calculated along with the time required by water to fall from a certain height to another height.
Concept introduction:
The exit velocity of any liquid flowing in a tank and passing through a pipe is given as,
Here, g is the acceleration due to gravity and y is the height or the distance covered by liquid from initial to final point.
The flow rate is given as,
Q = Flow rate of liquid
A = Area of tank/pipe
v = Velocity of liquid
The pressure head at the point B is given by the difference between the atmospheric pressure and the pressure due to the length of the tube, i.e.,
Patm is the atmospheric pressure
PB is the pressure at point B
