Question

The figure shows asiphon, which is a device for removing liquid from a container. TubeABCmust 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 atA. The liquid has density 1000 kg/m3and negligible viscosity. The distances shown areh1= 26.0 cm,d= 15.0 cm, andh2= 49.0 cm.(a)With what speed does the liquid emerge from the tube atC?(b)If the atmospheric pressure is 1.00 x 105Pa, what is the pressure in the liquid at the topmost pointB?(c)Theoretically, what is the greatest possible heighth1that a siphon can lift water?

Explanation / Answer

Tube ABC must be filled but once this has been done, water will flow through the tube until the liquid surface in the container is level with the tube opening at A. The liquid has density p and negligible viscosity. a) With what speed does the liquid emerge from the tube at C b) what is the pressure at the topmost point at B c) What is the highest point h1 (theoretically) that a siphon can lift water. a) Speed at C depends upon the level difference between container in A and tube end at C which keeps varying with the flow. b) If we assume that A is in a container filled with water, level in container has atmospheric pressure and pressure at the topmost point in tube = atmospheric pressure less hdg, where h = difference in height between the topmost point and level in container containing A, d = density of liquid and g = acceleration due to gravity. c) h1 = 1 / dg atmosphere
