What is pitot tube and objective ?


Objective - To measure the velocity of flow at different points in a pipe.

Aim - To find the coefficient of pitot tube. To find the point velocity at the center of a tube for different flow rates . To plot velocity profile across the cross section of pipe.

Introduction - It is a device used for measuring the velocity of flow at any point in a pipe. It is based on the principle that if the velocity of flow at a point becomes zero, there is increase in pressure due to the convection of the kinetic energy into pressure energy. The pitot tube consists of a capillary tube, bent at right angel. The lower end, which is bent through so, is directed in the upstream direction.
