Fluid Dynamics of Fires

a). From the definition of pressure P, it can be expressed as, P= F/A, where F is the applied force and A is the cross sectional area of the surface of the material. Since the hydraulic cylinder has two radial cylinders the pressure at each cylinder can be expressed as taking the subscripts 1 & 2 to represent the cylinders, then at the smaller cylinder 1, P=F1/A1 and at larger cylinders 2, P= F2/A2. But A1= ? R12 and A2 =?? R22. From the law governing pressure in fluids, pressure at both cylinders is equal hence F1/A1= F2/A2. Thus force one can be represented in terms of force two as F1= F2 *A1/A2. Substituting the area, then F1= F2? R12/?…

Forced Convection (in a cross flow heat exchanger)

The aim of this lab is to determine the average convective heat transfer coefficient for forced convection of a fluid (air) past a copper tube, which is used as a heat transfer model. Introduction The general definition for convection may be summarized to this definition “energy transfer between the surface and fluid due to temperature difference” and this energy transfer by either forced (external, internal flow) or natural convection. Heat transfer by forced convection generally makes use of a fan, blower, or pump to provide high velocity fluid (gas or liquid). The high-velocity fluid results in a decreased thermal resistance across the boundary layer from the fluid to the heated surface. This, in turn, increases the amount of heat that…

Frictional loss in pipe

Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation, taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous forces between layers in a fluid. Generally the results obtain from the experiment do agree with the theoretical prediction and the discrepancy of the points as shown in the moody chart was relatively small. In the laminar flow and turbulent flow region where the frictional factor values are similar to the values in the moody chart. The relative roughness…

Measurement of fluid properties

In this course, you will conduct the experiments at the Fluid Mechanics Laboratory, by yourselves, without any help or instruction from the teaching assistants. You must read the lab sheet thoroughly and understand what you are expected to do (and why) for each experiment, before coming to the lab. At the end of each experiment, you will have to do certain calculations, present and plot (when asked) your results on the provided report sheets attached to the end of the lab sheet. The experiment and the report-writing will all take place in the lab within the time allocated to your group (total: 1 hour). You will not have any time to study the lab sheet during the lab hour, if…
