TRANSFERÊNCIA DE CALOR EM COPOS TÉRMICOS: um estudo de caso do copo Stanley®

Abstract

The objective of this work is to present the heat transfer processes that take place inside thermal cups, especially the Stanley® cup that is the monograph, aiming to demonstrate the temperature variations in relation to time to know the efficiency by putting cold water inside. of the container and leaving for tests for three hours, where the idea is that the minimum addition of temperature occurs. Heat transfer can occur in several areas of our daily lives and there are three different ways for this to happen which are through conduction, convection and radiation, where all of them will be explained during work. The project seeks to do a study on a Stanley® cup, a cup made of stainless steel, which has the ability to maintain the temperature of drinks for longer than the conventional one, the proposed work seeks to show with quantitative data collected during the experiments, the change in degrees Celsius of the Stanley® cup, this always taking into account the variables of the external environment of the tests. After collecting all the temperature measurements, it was possible to observe the variation of the Stanley® cup that had a total variation in the three hours and a comparison was also made with an acrylic cup, where placed under the same conditions, its total variation.
