A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

Steam distillation of cloves produced 0.53g of an oil which contained in its IR spectrum the functional groups O-H (at 3520 cm-1)‚ sp2 C-H (3080 – 3000 cm-1)‚ aliphatic C-H (2980 – 2940 cm-1)‚ and both alkene C=C (at 1640 cm-1) and aromatic C=C (at 1514 cm-1). The IR spectrum is attached to this report. These data are consistent with the structure of eugenol‚ shown in Figure 2 below: In addition‚ the IR of the product from the steam distillation of cloves closely corresponds with that of an

The Impact of Western media on African Cultures By Levis Kamau Introduction Pop music has become very much popular and widespread among the young people in Nairobi City. It is usually characterised by western behaviours and ways of doings of the west (developed countries) particularly the United States and Jamaica. It is very common to hear young people talking about the pop singers. You will always hear “I like that dance in the song….” “I wish I had such a cloak”

After the fall of the Roman Empire (5th – 6th century)‚ bathing was not common at all especially in Western Europe‚ Japan and Southwest Asia; Simply because of the decline in wealth and in technology. Taking a bath required a lot of time and effort. You had to get buckets of water and wait for the water to get hot enough so you could take a shower‚ then you had to make sure you had enough soap to bath with. After the 5th and 6th century bathing was considered temporary and not important. There are

ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical

roots of plants. In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation was to use an azeotrope to isolate the organic compound from a solid. The azeotrope

COMMENTARY - REINDEER AND ENGINE This poem‚ "Reindeer and Engine" is by Josephine Jacobsen. It is set in a ’Finnish forest track’ where a reindeer is being chassed by a train. It flees from the light of the train as it ’runs’ forward trying to escape. This is a narrative poem because it tells a story from an omniscient point of view. It is written in four stanza’s each one telling a different part of the story. The first idea we come across is that of light. ’The great round eye’ in the first line
