Pitot tube

A pitot tube is used to determine the velocit y of a fluid flowing through a pipe
Principle:pitot tube uses the principle based on bernoullies equation to measure the flow.
Most pitot tube consist of two tubes.one measure the static pressure and the other higher pressure.low pressure tube measure static pressure and Higher pressure tube measuresure the the static pressure plus pressure required to stop flow.
volumetric FlowFlow rate can be obtained using equation
      Q=KAV
K=flowflow coefgicient
A=c/s area
V=velocity of flowing fluid.

Types of Flow

Steady flow: the properties of fluid atevery point in the flow do not depend upon time, it is called a steady flow. Unsteady flow: the properties of fluid at every point in the flow do not depend upon time, it is called a unsteady flow. Uniform flow: The flow in which velocity do not change from point to point at any instant of time. Non uniform Flow: The flow in which velocity do change from point to point at any instant of time. Laminar Flow: the motion of the fluid particles of fluid is parallel to the pipe walls.or along a straight line. Turbulent flow: Motion of a fluid partical in zig zhag way ie do not parallel to pipe wall. Compressible flow: The flow in in which density of a fluid changes from point to point and spaces is called compressible flow. Incompressible flow: The flow in in which density of a fluid do not changes from point to point and spaces is called compressible flow. Newtonian flow: The flow in which shear stress of fluid is directly ptoportion
