Change in Pressure and Different Depths in a Static Fluid Lab Marcus Uchaker MET: 2050 January 26‚ 2012 Purpose: The purpose of this lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a balloon on the end of a manometer and measure the pressure at different depths in a large beaker filled with water. The next

Experiment 1 Fluid Flow In A Smooth Pipe Abstract In this experiment‚ three variable flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate are then observed from the three pressure gauges that can measure pressure at different range and recorded. The shift from laminar flow to turbulent flow is seen from the results recorded‚ but it is observed more clearly from the water-soluble dye experiment that was carried out by the demonstrator. Laminar flow

Fluid Mechanics Laboratory 2 Report Robby Joseph 14103508 1.0 Introduction This experiment was undertaken for the study of flow in pipes and the factors that affect it in both laminar and turbulent regimes. The transitional regime between laminar and turbulent flow will also be studied. The experiment was done using a pipe with a known diameter‚ and water was pumped in from a tank. Throughout the process‚ measurements of the quantity of water and time were taken as well as the hydraulic gradient

MAE130B Concept/Question/Comments Film: Channel Flow of a Compressible Fluid Due Date: March 15‚ 2013 Concept 1: Choking Choking occurs when the Mach number at the throat of a channel flow is equal to one. Conceptually choking is the phenomena where the flow in a channel transitions to sonic flow. Due to the conditions of choking‚ the velocity‚ density‚ and pressure can increase or decrease continuously through a sonic throat‚ and the flow does not need to be symmetrical. Another notable phenomena

Contrary to popular belief‚ identity is fluid. Julian Baggini believes that we are the sum of our parts‚ by using an analogy about water. “Water is nothing more than the hydrogen and oxygen atoms suitably arranged. Everything else in the universe is the same” (Baggini‚ 6). By this he is saying that we do not have a formal and straightforward unit of identity‚ and that there are numerous “parts” that add up to it. It could be said that our identity is a fixed thing‚ and that we as people have fixed
