Effect (or) Environmental Impact (or) Consequences of Ozone Layer Depletion :

 As the ozone layer gets deteriorated the harmful UV rays will reach the ground and cause various adverse effects. 




I. Effect On Human Health 

i) The UV- Rays damage genetic material in the skin cells which cause skin cancer. 

ii) For the fair skinned people life long exposure to the high level radiation of  UV rays increases the risk of non - melanin skin cancer.

iii) Prolonged human exposure to Uv-rays may lead to slow blindness called actinic keratitis. Enhanced level of UV ray could lead to more people suffering from cataracts.

iv) Human Exposure to UV- rays can suppress the Immune responses in humans and animals. It also reduces human resistivity leading to number of diseases such as cancer, allergies and some other infectious diseases. 




II) Effect on Aquatic Systems 
 

i) UV Rays  directly affect the aquatic forms such as phytoplankton, fish, larval crabs. 

ii) The phytoplankton consumes large amount of CO2.

Decrease in population of phytoplankton could have more amount of Co2 in the atmosphere which contributes to the global warming.



III) Effect on Materials 

Degradation of paints, plastics and other polymeric material will result in economic loss due to effects of  UV radiation.




IV) Effect on Climate 

The ozone depleting chemicals can contribute to the global warming i.e, increasing the average temperature of the earth's surface.

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR :  The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve.  The float chamber is ventilated to atmosphere.  This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet  manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves.  One is to allow air into the mixing chamber known as choke valve. The other is to al...

MELTING FURNACES FOR FERROUS METALS : CUPOLA AND ITS WORKING

Various types of melting furnaces are used in different foundry shops, depending upon the quantity of metal to be melted at a time, and the nature of work that is carried out in the shop.  The primary objective in cupola is to produce iron of desired composition, temperature and properties at the required rate in the most economical manner. Besides, this furnace has many distinct advantages over the other types, e.g., simplicity of operation, continuity of production, and increased output coupled with a high degree of efficiency.  Description Of a Cupola : The Cupola Furnace consists of a vertical, cylindrical steel sheet, 6 to 12 mm thick, and lined inside with acid refractory bricks or acid tamping clay. The refractory bricks or the tamping clay used consist of  silicon oxide acid (SiO2) and alumina (Al2O3). The lining is generally thicker in the lower where the temperatures encountered are higher than in the upper region. The shell is mounted either on a brick work fo...

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 objec...
