To determine method factor for a Duct
Calibration of Orifice Plate
To obtain the method through precise traversing in the fan testing duct setup for different flow conditions, and to plot the nature of velocity profile.
Precise Traversing in a Duct using Pitot Tube
The purpose of this experiment is to finding the velocity profile of air flow in a ventilation duct and estimation of average velocity of air from the different point measurements in a cross-section.
Performance Evaluation of Mine Evasee Present in a Ventilation System
To determine the performance of an evasee by finding the velocity of air-flow with the evasee attached and without it.
Fan Rating Test
The objective of the experiment is the determination of fan characteristics such as finding out the fan static and total pressures, power input to the fan and total efficiency of the fan for various flow rates at the rated speed.
