Abstract
The selection of pumps for thermal fluid installations is complex and without an established methodology, it is difficult to follow. As there isn't currently an established methodology to choose the right pump under established conditions given the thermal fluid installation and the needs this one has to offer and also because there is a lot of data for the correct selection. It's difficult to make the correct selection without a methodology to follow, and makes it necessary to establish a process to adhere to. There isn't a single way to follow, as calculations can be done by various methods, it highlights the need of a method to use under certain conditions knowing the advantages and disadvantages that are attributed to it.
This degree thesis presents a methodology to help select a pump for a thermal fluid installation, defining which option is best for each case. The method presented is judged and discussed. With this developed methodology it would be possible to save time selecting the suitable pump for a thermal fluid installation and reduce the chance of error selecting the pump, as it can be terrible error, if the pump is poorly chosen, such as starting with a type unsuitable for the operating temperature and continuing with the wrong model, impeller or motor, it can not only result in failure to meet expected production expectations or end-product quality, but also in equipment and facility hazards.
This study evaluates how the formulas, methods and correlations for calculating friction factors or pressure losses, compares to the best known, and shows their advantages and disadvantages whilst also using numerical examples to determine their error percentages. The developed methodology proposes which of the methods to calculate the head pressure is the best to use, judging it and valuing the good/bad aspect of it. This thesis includes a C++ program that calculates the pressure loss of thermal fluid installations. This document outlines clearly the various
