Fluid Mechanics Lab

The objective of this laboratory is to determine the various parameters related to fluid flow in pipes and in open channels. At present it is equipped with hydraulic benches & various stand-alone equipment to carry out experiments like determination of metacentric height of a floating vessel, verification of the Bernoulli’s energy equation, study of transition from laminar to turbulent flow, determination of velocity profile for pipeline flow, determination of coefficient of discharge for obstruction flow meter(venturimeter/orifice meter), determination of discharge coefficient  for various notches, determination of hydraulic coefficients for flow through an orifice, determination of friction coefficient for pipes of various diameters and calculation of minor head losses in pipes. The laboratory also houses sub sonic wind tunnel fitted with necessary instruments to measure lift & drag forces and pressure distribution during the flow over aerofoils & other objects. A specially designed boundary layer apparatus is also available to study the development of laminar and turbulent boundary layers. The laboratory also houses facilities for carrying out the study of flow over various objects in sub sonic wind tunnel, open channel  and boundary layer analysis.
