Explain with the aid of a diagram and Bernoulli’s equation how a siphon operates?

**physics**

Show how Bernoulli’s energy equation for a fluid can be derived by considering how the work done by the fluid moving from point 1 to point 2 is equal to the energy gained or lost by the fluid. You can assume the potential energy PE=mgh and the kinetic energy KE=0.5mv 2 , ...

Water fills and flows through an expanding pipeline that is inclined upwards. On the centreline of the pipe, Point 1 is 0.3 m below point 2. The velocities are V1 = 3.4 m/s and V2 = 1.7 m/s. The pressure at point 1 is 9300 N/m 2 . What is the pressure at point 2 assuming no ...
