You have a container like the one shown in figure 1 from which you want to extract liquid with the help of a siphon (inverted U-shaped tube). The siphon should be filled initially, but once this is done the liquid will flow until its level drops below opening A. The liquid has a density ?, and a negligible viscosity. Assume that the area of the container is very large compared to the area of the tube and that both the tube at C and the container itself at D are open to the atmosphere. a) Using Bernoulli's equation and comparing points "D" and "C", determine the speed with which the liquid flows in C. b) What is the gauge pressure of the liquid at the highest point (B)? c) What maximum height H can the highest point (B) of the tube have without ceasing to have flow?

liquid will flow until its level drops below opening A. The liquid has a density ?, and a

tube and that both the tube at C and the container itself at D are open to the atmosphere.
a) Using Bernoulli's equation and comparing points "D" and "C", determine the speed with which the liquid flows in C.
b) What is the gauge pressure of the liquid at the highest point (B)?
c) What maximum height H can the highest point (B) of the tube have without ceasing to have flow?
d) If the liquid of density ? is changed, for one with density ?2 where ? < ?2, will there be any change in velocity at C? If there is any change, write down with which liquid the highest speed is obtained in C, otherwise justify.
