The rotameter consists of a vertical tube with a hole in which the position of the buoy is considered vertical according to the flow rate through the tube (Fig. 3.41).<\/span> For known flow rates, buoys remain stationary<\/i> because of the vertical forces of differential pressure, gravity, viscosity,<\/span> <\/i> and the buoyancy will be balanced.<\/span> So the ability to balance itself from a buoy hanging by a wire and depending on the area can be determined.<\/span><\/p>\n

The down force (gravity minus the buoyant force) is constant and so the upward force (decreased pressure multiplied by the buoy) must also be constant.<\/span> Assuming non compressive flow, the result is as follows:<\/span>

Buoys can be made from various materials to obtain the required density difference (W f<\/sub> -W ff<\/sub> ) to measure specific liquids or gases.<\/span> Tube is often made from high-strength glass so that it can be done direct observation to the position of buoy.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
