Fluid Mechanics and Hydraulic Machines Laboratory
Overview
Fluid mechanics lab will enable the students to calibrate flow measuring devices, determine the force exerted by jet of water on vanes, measure discharge and head losses in pipes and understand the fluid pattern. It is a well-furnished laboratory with all the hydraulic machines like, turbines (Kaplan, Francis) Pelton wheel, Jet through vanes, weirs, notches, pumps from which students can understand the flow characteristics of a fluid and discharge properties. The total area of the lab is 230 sq. Meters.
Laboratory Area: 206.46 Sq. Mts
Laboratory Expenditure: Rs 18,67,200
