The objective of this laboratory is to studey the operating characteristics of hydraulic machines and flow devices. The laboratory is important for Mechanical Engineering, Civil Engineering and Electrical Engineering students. The major equipment focuses on the study and calibration of gauges, triangular notch, rectangular notch, Orificemeter Venturimeter and determination of Chezy’s constant and Darcy’s coefficient. In addition the performance test on hydraulic machines like centrifugal pump, Reciprocating pump, Petrol Wheel, Francis turbine and Kaplan turbine are also conducted. Experiments also include the study of stability of floating body, hydraulic ram and experimental determination of frictional head losses in pipes. All the experimental set up are available as self contained units. Besides there are many helpful laboratory demonstrations.
