if by Poiseuille’s Law, the greater the radius/diameter of a tube the faster the flow, why does water flow faster out of a hose when you put your thumb over the nozzle?
In: 7
It doesn’t flow any faster. It’ll still take the same amount of time to fill a given container. What putting your finger over the end does is increase the pressure at which the water leaves the hose. The volume of water is still the same.
