Figure shows a siphon , which is a device for removing liquid from a container. Tube ABC must initially be filled , but once this has been done , liquid will flow through the tube until the liquid surface in the container is level with the tube opening at A . The liquid has density 1000 kg//m^(3) and negligible viscosity . The distances shown are h_(1) = 25 cm d = 12 cm and h_(2) = 40 cm Theoretically , what is the greatest possible height h_(1) that a siphon can lift water ? |

Answer» Solution :Since `p_(B) ge 0` , we must LET `p_(air) - rho g ( h_(1) + d + h_(2)) ge 0 ` which yields `h_(1) LE h_(1 , "max") = (p_("air"))/(rho g) - d - h_(2) = 10.3 `m |
