Anyone made one of these? It’s a screen grab from a YouTube Video. You just lower it into the water and the siphon starts by itself.
But that takes <"all the fun"> out of it.You just lower it into the water and the siphon starts by itself.
They used to make these in one of our post-graduate courses (<"Physics SKE">?). They may still do it as exercise, but we don't have the course any more.Anyone made one of these?
...... A siphon “pulls” water out of a container because of a difference in pressure between the two open ends of the tube. The pressure (Ph) at a given depth below the surface of a liquid is equal to the atmospheric pressure at the surface of the water plus the pressure exerted by the liquid, which is proportional to the depth beneath the surface (ρgh).
Equation 1. Ph = Po + ρgh
I think it needs to be a fairly narrow bore tube to get the capillary effect, so not really useful for syphoning the tank etc.Ph = Pressure at a given depth below the surface of a liquid
Po = Atmospheric pressure at the surface of the liquid
ρ = Density of the liquid
g = Acceleration due to gravity constant
h = Depth beneath the surface of the liquid
Licking my fingers after scooping out the microworm culture, like any reasonable person!Then how do you get your probiotics?
