Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily

situation for thick pipes is‚ however‚ more complex. [pic] The figure shown above represents the condition in a thick walled pipe. The area for heat flow is proportional to the radius – as may be seen‚ the area at the outside wall of the pipe is much greater than the middle. As a result the temperature gradient is inversely proportional to the radius. The heat flow ‘per unit length of pipe’ at any radius r‚ is [pic] cf. [pic] Note: Area‚[pic] Note there is no length of pipe (l) in this equation

Evolution of the Jet Engine Thought the course of time man has constantly sought to better both himself and mankind through creation and invention. From the first time a caveman rubbed to sticks together and discovered fire to the design and development of the Saturn 5 rocket which propelled by that same fire carried man from the earth to the moon. One can argue over whether on not this invention or that was the greatest. I intend to focus my attention on evolution of just one of those technologies

experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained within the calorimeter (1). Early

Internal Combustion Engines An internal-combustion engine is a heat engine that burns fuel and air inside a combustion chamber located within the engine proper. Simply stated‚ a heat engine is an engine that converts heat energy to mechanical energy. The internal- combustion engine should be distinguished from the external- combustion engine‚ for example‚ the steam engine and the Stirling engine‚ which burns fuel outside the prime mover‚ that is‚ the device that actually produces mechanical

systems P1) Oil - Vegetable Oil Vegetable oils are a triglyceride that is extracted from agricultural crops‚ these oils are natural products and therefore their chemical composition changes from one crop to another. They are used in engines and chainsaws as a lubricant instead of petroleum based oils. Canola Oil – made from rapeseed – is an example of a vegetable oil‚ it is cleaner than petroleum based oils and has less health risks as petroleum oils are commonly carcinogens and can
