Water flows smoothly and falls on top of a plat surface (anupside-down baking tray in the picture). Two interestingphenomena are involved here: A) vena contracta; and B)hydraulic jump. Google these

terms and choose one to study inyour video: A) Explain phenomenon A in the picture. Study water column diameter versus z position based on mass conservation. Make it quantitative. Compare your theory with your own experimental measurements. B) Explain phenomenon B in the picture. Study the diameter of the circle on the flat surface versus flow rate based on mass conservation. Make it quantitative Compare your theory with your own experimental measurements.
