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

This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

PERTH COLLEGE UHI 12 INSTRUMENTATION OF A WIND TUNNEL PROJECT BEng(Hons) Gaurab Ghosal ABSTRACT The wind tunnel being built in Scone airport is a closed loop wind tunnel. On completion this will provide a much needed facility for education purpose as it can be used by engineering students for aerodynamic evaluations. To conduct these evaluation proper evaluating tools needs to be setup. In this section the possible instruments that can be setup in this wind tunnel has been evaluated with

a turbo-machine in which work is done to increase the total pressure of the fluid leaving the device. This is achieved by a rotor or impeller‚ which is driven by an external source of power to move a row of blades so as to impart energy to the fluid. A centrifugal fan‚ the focus of this experiment‚ consists basically of three components: an air inlet duct‚ an impeller and a volute casing. The inlet duct conducts the fluid (in this case‚ it is air) into the impeller. The air then passes through a

1. Introduction The flow of fluid in a pipe under pressure is used to reach many goals. A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size‚ capacity and material of the pipe for a system. In engineering and industry‚ the understanding of pipe flow is required for the control‚ transport‚ measure and storage of water or other fluids. When a fluid is flowing through a pipe‚ it exerts a viscous

Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl α V And for turbulent flow : Hl α Vn Where : Hl :is the loss of pressure head . V : the mean velocity of flow . n : an index that lies

Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift‚ displacement‚ and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary)‚ and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources‚ including manual operation‚ electricity
