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

Centrifugal pump construction and working.

Image
Centrifugal pump consist of the following parts 1)Inlet and outlet pipe 2)Casing 3)Impeller 4) Vanes. Working principle of Centrifugal pump:  Centrifugal pump creates an increase in pressure by transfer of mechanical energy from the electrical motor to the fluid through the rotating impeller. Inlet and outlet pipe.- One end of the inlet pipe is dipped in to the fluid fitted with a strainar and other end is connected to the casing. Similaraly one end of oulet pipe connected to casing and other to the discharge tub. Casing: Casing is the outermost part of the centrifugal pump. cross sectional area of the pump is goes on increasing along the sdischarge side.casing is generally made up of a stell or cast iron. Impeller- Impeller is the rotating part of the pump.which have vanes for pushing fluids in the casing.sometimes there will be guide vanes are also provided to guide the flow.Impeller is situated in the casing. Working: Suction pipe suck the water fro
