Disaster Management - Cyclone /Tycoon/ Hurricanes/ Willy Willies

Cyclone :

Cyclone is a meteorological phenomenon, intense depressions forming over the open oceans and moving towards the land. On reaching the shores, it move into the interior of the land or along the shore lines.

Thus the Cyclones are the most powerful, destructive, dangerous atmospheric storms on the earth. The cyclone once formed may be active from days to weeks and their speed varies between 180-500 km/hour.

Occurrence :

Tropical Cyclones in the warm oceans are formed because of heat and moisture. The main requirement of formation of the tropical cyclone is that the sea surface temperature (SST) must be below 25*C. The tropical cyclones move like a spinning top at the speed of 10-30 km/hour.

Effect of Cyclone :

The damage depends on the intensity of cyclone. The damage to human life, crops, roads, transport, communications, tanks, canals, livestock could be heavy.

Cyclone Occurrence slow down the developmental activities of the area.

Cyclone Management :

1. Satellite images are used by meteorological departments for forecasting the weather conditions, which reveal the strength and intensity of the storm.

2. Radar System is used to detect the cyclone and is being used for cyclone warning.

3. For observing the exact location of cyclone, every half an hour satellite pictures are analyzed.

4. It is difficult to stop the formation of cyclones, but the effect of which is minimized by planting more trees on the coastal belt, construction of dams, dykes, embankments, wind breaks.

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

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

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.
