1. Objective The aim of this laboratory experiment is to analyse the rate of heat transfer losses through convection and radiation separately from a cylindrical glass rod suspended in a pressure vessel. The variation of the dimensionless quantities; Nusselt number‚ Prandtl number and Grashof Number‚ with Pressure are to be analysed graphically as well. The experimental graph of log10(Nu) vs log10(Gr.Pr) should be plotted and analysed against the graph of the empirical equations. 2. Introduction:

Forced Convection Heat Transfer I. Introduction This laboratory deals with forced convection‚ forced convection can be considered as a staple of heat transfer. That is to say that forced convection can be found in almost any heat transfer problem‚ and thus understanding its importance and how it affects a given problem is one of the more important learning objectives/outcomes of heat transfer. When dealing with forced convection the most important section‚ after understanding how convection

Conventional Ovens vs. Microwave Ovens Modern technology has touched everyone in some form or fashion. This includes everyday items such as the conventional and microwave oven. Both cook food‚ however‚ each cooks in its own particular way. Conventional oven cooks at a slower pace and the microwave speeds up cooking time by using specially prepared‚ packed entrees. This paper will compare and contrast conventional ovens and microwave ovens. Conventional ovens can be found in a majority of

to buy her a birthday gift.I have two items in my mind.They are an electric oven and digital camera.I saw these two items in an advertisement in the newspaper. The electric oven costs RM520.00.It is very convenient for Mum to bake a cake and biscuits.It also has a multi-purpose function.Other than baking‚the oven can be used for girling chicken and meat.It can also be used to make a toast and even bake fresh bread.The oven is also easy to clean after use. As for the digital camera‚it also costs RM520

If I was a Kitchen Oven If I had to be a kitchen utensil or appliance I would be an oven‚ because it have different types of things it’s used for on an everyday bases. Also it can be electric or gas. Ovens even comes in different colors shapes and sizes. You can use it every day if you had to. Almost anyone can use an oven. Sometimes people don’t realize how easy it is to use an oven. When it comes time to use one‚ some people

3rd Year Thermodynamics Lab Report Mechanical Engineering Science 10 Forced Convection (in a cross flow heat exchanger) Summary 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

Forced and free convection Laboratory Introduction Convection‚ along with conduction and radiation is one of the three ways in which heat is transferred. In convection‚ heat can be exchanged from one fluid to another. In this experiment‚ a heated plate is in contact with air inside a rectangular cross section duct. The air is heated by conduction from the heated plate. The density of the air decreases as it is heated and this makes the warm air rise. Colder air‚ which in turn is less dense‚ then
