Describe how atmospheric circulation gives rise to the formation of high and low pressure area? The origins of the creation of areas of differing pressures can be seen to start with the sun. As the sun gives off radiation some is absorbed by the earth‚ however this absorption is centred on the equator and therefore creates a disparity between the heat of the equator and tropics and the rest of the globe. Between 450 North and 300 South there is a positive heat budget whereas outside these regions

‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss. Low pressure atmospheric systems are also known as depressions or cyclones and they form in mid- and high-latitudes. They are formed by the mixing of cold and warm air‚ the warm air is lighter‚ so it rises above the denser‚ cold air and forms a centre of low pressure. High pressure atmospheric systems are also known as anticyclones and have very different characteristics to depressions. Anticyclones

Cooling towers are a very important part of many chemical plants. They represent a relatively inexpensive and dependable means of removing low grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. [pic] Types of Cooling Towers |[pic]

Thermodynamics - Assignment 4 D3 SS Sultana – a Mississippi River steamboat paddle wheeler that exploded on April 27‚ 1865 in the greatest maritime disaster in United States history. Around 1‚600 of Sultanas 2‚400 passengers were killed when THREE of the ships four boilers exploded and Sultana sank near Memphis‚ Tennessee. The cause of the explosion was a leaky and poorly repaired steam boiler. There was reason to believe allowable working steam pressure was exceeded in an attempt to overcome
