Pipe Network Energy Losses Allan Valdez 1 Abstract This lab report evaluates a pipe network with changing fittings to analyze the various minor losses. Each fitting has a theoretical loss coefficient determined experimentally with this pipe network. The result demonstrated that the experimental results are about the same as the accepted values for each fitting. Nomenclature : K Fitting loss coefficient h L Head Loss V Velocity g Gravity constant f Time. L Length D Diameter Introduction This experiment is named Pipe Network Energy Losses. The objective is to examine the loss coefficients of various fittings in pipe flow and to compare these values with the accepted values [ CITATION Moh23 \l 1033 ]. The purpose of this lab is to utilize an adjusted Bernoulli equation that accounts for head loss, the pipe network dimensions, and the measured flow rate to calculate the loss coefficient for each fitting. This lab was completed on November 9, 2023, by Allan Valdez as a requirement for a fluid mechanics laboratory course at San Diego State University.

Pipe Network Energy Losses Allan Valdez 2 The introduction begins by stating the name of the experiment. The objective statement from the experiment handout is repeated, preceded by “The purpose of this lab is……” The name of the person performing the experiment is stated along with the location and date. The fact that it was a requirement for this course is stated. (1) Theory In this experiment, a pipe network with a mitre, a small radius bend, an enlargement, a contraction, and a large radius bend are analyzed for the energy losses occurring. The pipe network is a simple example of the various pipe fittings used in everyday fluid transportation. The fittings are separated from the straight portion of pipping since the losses occurring are different. The straight portion are major losses while the fittings are minor losses. The minor losses produce proportional loss coefficients to the defining geometry of the fitting. For example, the enlargement’s loss coefficient is proportional to the area of the small area pipe divided by the large area pipe. Accepted values for various fitting geometry is published. This section discusses the theory and accepted empirical data used for the experiment, briefly but completely. All equations used are included, with definition of all terms. The way in which the lab results are used to compare with the theory is described. Derivations of equations from textbooks are not included. However, if you derive the equations by yourself, you need to list the derivation in the Appendix section (1). The equations must be typed, do not use photos, scans from equations, generated by a mathematical interpreter of your preference; also they must be numbered. For example equation 1 is a very important equation, and equation 2 is a more general form of Equation.

Drawings, identified by figure numbers, are appropriate. The procedure needs to be described in detail (1). Even though picture may be appropriate to describe the equipment usually it is not enough, you should describe the main features of the equipment and setting that may affect the experiment outcome. Figure 1: H1D Volumetric Hydraulic Bench.. Adapted from ref. (2) Figure 1 shows the H1D volumetric hydraulic bench manufactured by TecEquipment. Only show a picture is not enough, other information may be relevant for the experiment for example: Equipment: Volumetric Hydraulic Bench
