Effects ( Impacts ) Of Acid Rain :

Acid rain causes a number of harmful effects. Some of the adverse effects are as follows.

1. Effects of acid rain on human beings :

i) Acidic rain has been found to be very dangerous to the living organisms as it can very dangerous to the living organisms as it can destroy life. Human nervous system, respiratory system and digestive system are affected by acid rain.

ii) It also causes the premature death from the heart and lung disorders such as asthma and bronchitis.

2. Effects of acid rain on Buildings :

i) The Taj Mahal in Agra Suffering at present due to So2 and H2So4 acid fumes released from Mathura refinery. Crystals of CuSo4 & MgSo4 are formed as a result of corrosion caused by acid rain.

ii) Acid Rai corrodes houses, monuments, statues, bridges and fences. British Parliament building also suffered damage due to H2So4 rains.

iii) Acid rain and dry deposition of acidic particles contribute to the corrosion of metals, and the deterioration of paint and stone. These Effects seriously reduce the value of buildings, bridges and cultural Objects.

iv) Dry deposition Of acidic compounds can also dirty buildings and other structures, leading to increased maintenance costs.

3) Effects of Acid Rain On Terrestrial and Lake Ecosystem :

i) The effect of acid precipitation on terrestrial vegetation reduces rate of photosynthesis and growth and increased sensitivity to drought and disease.

ii) Acid Rain severely retards the growth of crops such as beans, radish, potato, spinach and carrots etc.,

iii) Acid rain causes a number of complications in ponds, rivers and lakes where it accumulates as acid snow. It causes a significant reduction in fish population.

iv) Black flies, mosquitoes, deer flies and the aquatic worms occur abundantly where fishes are eliminated due to acid deposition.

v) The activity of the bacteria and other microscopic animals is reduced in acidic water. So the dead materials and other accumulated substances lying on the bottom of lakes are not rapidly decomposed. Thus essential nutrients such as nitrogen and phosphorus stay locked up in dead wastages. Biomass production is reduced and fish population declines.

ELECTRICAL COMPARATORS AND ITS WORKING

Electrical Comparators are used as a means of detecting and amplifying small movements of a work contacting elements. An electrical comparator consists essentially of a pick-up head or transducer for converting a displacement into a corresponding change in current and a meter or recorder connected in the circuit to indicate the electrical change, calibrated to show in terms of displacement. Generally, an amplifier is needed to provide the requisite sensitivity and to match the characteristics of different parts of the circuit. Electrical comparators can be classified according to the electrical principle used in the pick-up head. Most of the comparators use either a differential transformer, an inductance bridge, a strain gauge or a capacitor as a means of detecting movement of the gauging element. There are different types of electrical comparators. One kind called an electrolimit gauge is used to check or measure the outside diameter of a roll. The object to be checked is place

THROTTLE GOVERNING OF STEAM TURBINES

Steam Pressure at inlet to a steam turbine is reduced by throttling process to maintain the speed of the turbine constant at part load and hence this method of governing is called "Throttle Governing". Construction : Throttle governing system consists of a centrifugal governor, a lever , an oil pump , a pilot piston , control valve , a relay piston and a throttle valve. The throttle valve is moved by a relay piston. The relay piston is actuated by pilot piston control valve. There are two piston valves covering ports in the pilot piston control valve without any overlap. These piston valves are operated by lubricating oil supplied by a gear pump at 2 to 4 bar. The oil returns to the drain from this chamber. Working : When the turbine works on full rated load, the throttle valve will remain open. When the load is decreased, the energy output of the turbine becomes in excess and the turbine shaft speed increases. Hence, governor sleeve will lift. The upward movement of the

Advantages And Disadvantages Of Air Refrigeration System :

Advantages Of Air Refrigeration : 1. The refrigerant used namely air is cheap and easily available. 2. There is no danger of fire or toxic effects due to leakages. 3. The weight to ton of refrigeration ratio is less as compared to other systems. Disadvantages Of Air Refrigeration : 1. The quantity of Refrigerant used per ton of refrigeration is high as compared to other systems. 2. The COP of the system is very low. Therefore running cost is high. 3. The danger of frosting at the expander valves is more as the air contains moisture content.
