Pitot Tube Apparatus
The Pitot Tube Apparatus by Atto Labware is a precision educational apparatus designed to measure fluid velocity at different points in a flow stream using a Pitot-static tube. This system enables verification of Bernoulli’s principle and allows students to determine the velocity profile across pipes or ducts. It is ideal for use in Fluid Mechanics and Aerodynamics laboratories to study steady and fully developed flow conditions.
Educational Objectives
Students and researchers will be able to:
-
Measure point velocity using a Pitot-static tube and manometer.
-
Verify Bernoulli’s equation relating pressure and velocity head.
-
Determine velocity distribution across a pipe or duct cross-section.
-
Calculate volumetric flow rate and compare with theoretical predictions.
-
Understand the relationship between static, dynamic, and total pressure.
Performance Measurement
-
Measurement of static and total pressure using a Pitot-static tube.
-
