ABSTRACT

The following experiment is about the Statistical Analysis of the Gravimetrical Flow Measurements. For this, we used the Gravimetric Bench, we are going to use it to calculate the necessary flow measures. We can first find the valueof our mass flow, which depends on the time and the mass used for them to find the volumetric flow, which also depends on the mass flow and the density of the fluid used, in this case we used water. The results for the Mass Flow Rate and the Volumetric Flow Rate where: , for the first run, , in the second run, , in the third run, , in the fourth run.

INTRODUCTION

As engineering students that we must have the capability, you can perform statistical analysis that allows us to solve engineering problems. In this work we would familiarize with gravimetricmeasurement method to calculate the flow in a tank. In the experimental part we observe the behavior of fluid when mass is added.

The primary objective of this experiment was working with familiarization of the experimental method and statistical analysis data. It’s very important the representative value that provides a measure of the variation in the measured data. This is being...
