In hydrostatics, pressure measurement with U-gauges and their relationship to density is a
\nwell-known experiment. Very little is studied or experimented with the dynamics of the movement of a
\nliquid in a U-tube probably due to its theoretical complexity but, after all, it is a simple damped
\noscillating system. In this paper we present a relatively simple experiment that allows studying in
\nsome detail the dynamics of the movement of a liquid in a U-tube when an initial pressure gradient
\nis applied. In order to record the information of the column displacement as a function of time we
\nhave developed a position sensor system based on a solar cell that allows the recording of the
\nexperiment using a simple data acquisition system.<\/p>\n","protected":false},"excerpt":{"rendered":"
