Abstract
Whenever a dusty or slurry air passes through the L-type pitot tube its impurities struck at 900 bend, resulting in the partially choking of the air flow through this device. And eventually its accuracy is decreased with the passage of time. Alternatively, such type of obstruction of the air flow can be avoided by using S-type pitot tube. Keeping this in mind, in the present work we had used S-type pitot tube of diameters ranging from 1.23 mm to 9.54 mm to test against the standard (L-type) pitot tube to control the accuracy of S-type pitot tube co-efficient. An experimental work has been carried out in a simulated wind tunnel environment. The results of the present work showed that there a slight dip over a velocity range of 3 to 14 m/s. Further, it is observed that for higher Reynolds numbers or at higher velocities of the air (more than 14 m/s) the co-efficient performance of S-pitot tube is found almost constant.
