Hi guys, Could anyone explain Bernoulli's Principle to me so that it makes sense from an alternative point of view? http://hyperphysics.phy-astr.gsu.edu/hbase/pber.html I can make sense of the maths but I'm trying to understand what actually happens so I can visualise it. At first it didn't make sense to me how the pressure could drop. To me it seemed like it would remain the same, halving the volume would mean the mass of fluid travels twice as fast and pressure remains the same. I think I am starting to understand though, something to do with the force generated by a reduction of half volume produces a velocity of more than double? As F= MA, the integration of V, V2/2 x ρ let ρ = 1 and discard If V = 5, then V2/2 = 12.5 If V = 10, then V2/2 = 50 So doubling the velocity required 4 times the force? Am I close to getting it? Cheers.
