# MAAE 2300 Study Guide - Volumetric Flow Rate, Venturi Effect, Corrected Flow

## Document Summary

The pressure changes along a linearly deformed throat were measured as a function of the change of height in an array of monometers. Performing the experiment at two arbitrary speeds showed the pressure change was directly related to the cross sectional area of the venturi. Meter, the data points forming the same curve, offset only by the relative vacuum powers the experiment was performed at. Two venturi coefficients were calculated, at 0. 96 and 0. 97 respectively. Thus it can be assumed that the no-slip condition of fluid flow has a greater effect within the smaller area presented by the venturi meter"s throat. Patm = atmospheric pressure, usually in pascals : 101325 pa [supplied in lab] Air = density of air in kg/m3 : 1. 225kg/m3 [1] Water = density of water in kg/m3 : 1000 kg/m3 [2] Vc= venturi coefficient, found by comparing the ideal and actual volume flow rates. Qideal = ideal volume flow rate, in m3/s.
