Could someone explain to me how a Siphon works using Bernoulli's equation. Why would one beaker have to have a higher height than the other beaker? My thoughts were that a Pressure differential is needed for water to flow, so the input and the output pressures must be different. In addition, water flows from higher pressure to lower pressure Using Bernoullis' equation 1/2ρv2 +mgh + P = constant Why does water flow from the beaker with a greater height into the beaker with the lower height? Isn't pressure B1 ( beaker with the lower height) greater than the pressure B2 (beaker with the greater height). And that water would move from the lower height to the higher height due to water wanting to flow from greater pressure to lower pressure?
