1. Abstract
This experiment is demonstrated to calculate the convection heat transfer coefficient by using two ways of calculation. One is the method using Newton's cooling law and another is the method using Nusselt number. For the first method, temperature change has to be measured from the experiment. Pressure change has to be measured for the second one. By Bernoulli Equation, the velocity of the flow can be calculated so that Reynold's number can be gotten. It can be tell whether the flow is laminar, turbulent or transition flow by Reynold's number and appropriate composition of Reynold's number and Prandtl number allow us to calculate Nusselt number. From Nusselt number, convevtion heat transfer coefficient can be calculated. The reasons of difference between two coefficients are discussed at the end of this report and some basic knowledge can be found at 8.Appendices.
2. Introduction
Heat is difined as energy transferred between two objects because of the temperature difference between them.
