Printed in Great Britain HEAT TRANSFER IN AN ANNULUS WITH VARIABLE CIRCUMFERENTIAL HEAT FLUX? W. A. SUTHERLAND: and W. M. KAYS§ (Received 10 March 1964) Abstract-An analysis of heat transfer in a concentric circular tube annulus with an arbitrarily prescribed heat flux around the periphery of either wall‚ or both walls‚ is presented. Solutions have been obtained for the hydrodynamically and thermally fully developed condition for constant heat rate per unit of tube length‚ for both

The Latent Heat of Vaporization of Water The Latent Heat of Vaporization of Water Aim: The aim is to determine the latent heat of vaporization of water by doing an experiment of boiling water. Theory: The latent heat of vaporization is the amount of energy that is required to transfer a kg of liquid from the liquid state to the gaseous state. This transformation appears‚ when water is heated. The temperature of the water keeps increasing‚ until it

Steel and heat treatment MILD STEEL Mild steel is also called plain carbon steel. It is the most common type of steel and it price is pretty low. Its composition is around about 0.05%-0.29% carbon content. Mild steel has a relatively low tensile strength but the surface can be hardened through carburizing. It is mostly used where large amounts of steel needs to be formed eg structural steel MEDIUM CARBON STEEL Medium carbon steel has great wear resistance and is used for forged automotive

Ten Minutes of Specific Heat Remi Adams East Rowan High School AP Environmental Science Abstract Specific heat and climate were the primary focus of this lab. Specific heat is defined as “the measure of the ability of a substance to change temperature”. The purpose for carrying out this lab was to determine the specific heat/rates of both soil and water‚ and then comparing them. Students also were to relate specific heat to climate. Students were to determine which substance expressed

similar compositions by subjecting them to different temperatures for different periods of time. The experiment showed that the strength and hardness of the samples increased when they were allowed to age for longer time under a given temperature and the rate of increase in hardness was directly proportional with the ageing temperature.

the form of a heat wave that swept across the Great Plains and the Mid West in July 1995. It represented the affect of the disaster and also the problems faced by the healthcare and public protection authorities in coping up with the situation during and after the disaster. The number of lives lost was estimated to be 522 and 733‚ count given by two sources. The heat wave struck Chicago on 11 July and it left on 16th July leading to an annihilating situation in the city with a huge loss to life. The

Saving the World Habitat loss isn’t only hurting our plant and animals around the world. Humans are also a part of the life cycle and depend on all of these damaged natural resources to maintain the life we live every day. Properly functioning natural systems give us the ability to breath‚ create safe food and drinking water and provide us with everything we need to survive. Each species plays an important role in its ecosystem. Habitat loss and degradation is one of the biggest threats to animals
