Piezometer

Home -> Lecture Notes -> Fluid Mechanics -> Unit-I


For measuring pressure inside a vessel or pipe in which liquid is there, a tube may be attached to the walls of the container (or pipe) in which the liquid resides so liquid can rise in the tube. By determining the height to which liquid rises and using the relation P1 = ρgh, gauge pressure of the liquid can be determined. Such a device is known as piezometer. To avoid capillary effects, a piezometer's tube should be about 1/2 inch or greater.
















It is important that the opening of the device to be tangential to any fluid motion, otherwise an erroneous reading will result.
