Answer All the Questions

XI. Read the following passage and answer all the questions that follow:

 Biodiesel is natural oil that’s taken out of several non-edible oil-bearing plants. It undergoes organic and chemical processes to yield fatty acid esters, or a diesel-like product, which can be blended with normal diesel. Experts predict that, like ethanol; biodiesel can be used by mixing it with anything.

In India, the focus is on a wild plant, Jatropha Curcas, which can grow in most places since it requires little water and fertilizer, can survive on infertile soils, and is not eaten by cattle. It’s also pest-resistant and has a high-seed yield that continues to be produced for 30-40 years. The seeds are crucial here, for they have a high oil content of 35-40 per cent and the kernels an even higher 50-60 per cent.

Biodiesel, blended with petroleum diesel, has low sulphur content, reduces unburnt hydrocarbons and produces less carbon monoxide and particulate matter. It is already Euro-IV compliant, even as India is gearing up to adopt Euro-III standards. And biodiesel could cost half of what normal diesel does.

Despite enthusiasm among private and public agencies, there remains a number of problems with biodiesel. A major hurdle is in its commercial production. The cost of the oil procurement, storage, transportation and extraction accounts for a major proportion – and these can be high. It has technical limitations too. Its high viscosity makes it less useful at lower temperatures. For long term storage in hot and humid conditions, extra costs have to be incurred to prevent bacterial growth. Since biodiesel degrades rubber, fuel filters may require frequent changes, hiking maintenance costs.

 

I.                             Answer the following questions:

1.   What is Biodiesel?

2.   Why is Jatropha Curcas the preferred plant for biodiesel in India?

3.   What are the advantages of biodiesel?

4.   What are the problems related to biodiesel?

 

II.State whether the following sentences are true or false:

1.     Jatropha Curcas cannot survive on infertile soil.

2.     Blended with petroleum diesel, biodiesel has high sulphur content.

3.     Biodiesel has technical limitations also.

 

III.         Fill in the blanks:

1.   Biodiesel undergoes organic and chemical processes to yield ------------------

2.   Its high viscosity makes it less useful at ---------------------

3.   Fuel filters may require frequent changes since biodiesel degrades --------------- 

 

XII.  (A) You have recently been to the Coramandal Cement Industries Ltd. on an industrial visit. Your Head of the Department has asked you to prepare a report on your visit. Your report should clearly state the purpose of the visit, the observations you have made and the preparatory measures taken. The report should be submitted in the correct format along with the title page. Assume yourself to be Michael.

OR

(B)   Read the following passage and draw a flow chart.

          The earth contains a large number of metals which are useful to man. One of the most important of these is iron. The iron ore which we find in the earth is not pure. It contains some impurities which we must remove by smelting. The process of smelting consists of heating the ore in a blast furnace with coke and limestone and reducing it to metal. Blasts of hot air enter the furnace from the bottom and provide the oxygen which is necessary for the reduction of the ore. The ore becomes molten, and its oxides combine with carbon from a liquid slag. This floats on top of the molten iron, and passes out of the furnace through a tap. The metal which remains is pig iron.

     We can melt this down again in another furnace - a cupola - with more coke and limestone, and tap it out into a ladle or directly into moulds. This is cast iron.

 

XIV. (A) Write a letter of application along with your resume in response to the following advertisement:

XVI. (A)  Read the following passage carefully and write notes in a     format which you consider necessary.

 

         The two main things that make aircraft engineering difficult are, making every component reliable and light. The fact that aeroplanes cannot be stopped mid-air makes it perhaps a matter of life and death.

The designer or the "stress man" keeps all practical aspects like the power of the engine, radio navigational instruments, passenger's seats, freight room and of course, the passengers themselves in designing the aircraft. So the structure of the aircraft has to be as small and light as safety and efficiency will allow. The designer must calculate the normal load that each part will bear. This specialist is called the 'stress man'. He takes into account of any unusual stress that may be put on the part as a precaution against errors in manufacture, accidental damage, etc.

The stress man's calculations go to the designer of the part, and he must make it as strong as the stress man says is necessary. One or two samples are always tested to prove that they are as strong as the designer intended. Each separate part is tested, then a whole assembly - for example, a complete wing, and finally the whole aeroplane. When a new type of aeroplane is being made, normally only one of the first three will be flown. Two will be destroyed on the ground in structural tests. The third one will be tested in the air.

Two kinds of ground strength tests are carried out. The first is to find the resistance to loading of the wings, tail, etc. until they reach their maximum load and collapse. The other test is for fatigue strength. Relatively small loads are applied thousands of times. Each may be well under what the structure could stand as a single load, but many repetitions can result in collapse. One form of this test is done on the passenger cabin. It is filled with air at high pressure as for high-altitude flying and completely submerged in a large tank of water while the test is going on. The surrounding water prevents the cabin from bursting like a bomb if there is a failure.

When a plane has passed all the tests it can get a government certificate of airworthiness, without which it is illegal to fly, except for test flying.

Making the working parts reliable is as difficult as making the structure strong enough. The flying controls, the electrical equipment, the fire precautions, etc. must not only be light in weight, but must work both at high altitudes where the temperature may be below freezing point and in the hot air of an airfield in the tropics.

To solve all these problems the aircraft industry has a large number of research workers, with elaborate laboratories and test houses, and new materials to give the best strength in relation to weight, which are constantly being tested.

(B)   Write a short paragraph in not more than 150 words on the topic:    ‘Man has become a slave of technology’. Do you agree with the idea? If yes, justify yourself with reasonable points. If no, substantiate your view with valid points.
