Online Experiment: Continuity equation
This online experiment of the University of colorado clearly shows how the flow velocity of a fluid changes according to the cross-sectional area of the pipe. For this purpose, the pipe can be reshaped at various positions and the volume flow can be adjusted. The velocity, flow rate and cross-sectional area can be measured virtually at any point of the pipe.
Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.
