Natural draft and forced draft cooling systems.

        Natural draft and forced draft cooling systems


 Natural draft and forced draft cooling systems are two types of cooling systems that are commonly used in industrial and power plants. Both systems are used to remove excess heat from equipment and processes, but they differ in the way that air is circulated.


 Natural Draft Cooling System:

                                                    A natural draft cooling system uses the natural convection currents created by the difference in temperature between the hot exhaust gases and the surrounding atmosphere to circulate air through the cooling system. The warm air rises, and the cooler air is drawn in from below to replace it. The cooling tower is typically tall and has a large diameter, which allows for maximum air circulation. This type of cooling system is less energy-efficient than forced draft cooling but is less expensive to operate.










 Forced Draft Cooling System:

                                        A forced draft cooling system uses fans or blowers to force air through the cooling system. The fans or blowers create a positive pressure that forces the air to move through the system. The cooling tower is typically smaller in diameter and has a taller height than a natural draft cooling tower. This type of cooling system is more energy-efficient than natural draft cooling but is more expensive to operate. The choice between natural draft and forced draft cooling systems depends on several factors, including the size of the system, the ambient conditions, and the required efficiency. Natural draft cooling systems are typically used in smaller systems, while forced draft cooling systems are used in larger industrial and power plant applications. The type of cooling system used will have a significant impact on the energy consumption and operating costs of the plant.

Creativity:                     Entrepreneurs usually have the knack to pin down a lot of ideas and act on them. Not necessarily every idea might be a hit. But the experience obtained is gold. Creativity helps in coming up with new solutions for the problems at hand and allows one to think of solutions that are out of the box. It also gives an entrepreneur the ability to devise new products for similar markets to the ones he’s currently playing in.    2) Professionalism:                                 Professionalism is a quality which all good entrepreneurs must possess. An entrepreneurs mannerisms and behavior with their employees and clientele goes a long way in and discipline. Self-di

Subject:-Measurement & Metrology, Angle measuring instruments:-Sine bar , Clinometer , Bevel Protector.

  Angle measuring instrument:-   →   The instrument which is used for measurement the slope of any object surface is called angle measuring instrument . →T here are 3 types of angle measuring instrument.     ( I)Sine bar                   ( II)Clinometer     ( III)Bevel Protector                         SINE BAR:- → sine bar is an angle-measuring instrument that measures slope of any object with the help of slip gases and a dial indicator. → it is a steel piece mounted over two hardened steel cylindrical roller having equal diameter. → To make it lighter in weight small holes are drilled along steel piece. Principle:- →The working of sine bar is based on the princiople of trigonometry.  In this one roller is placed over combination of slip gauges and another is placed over table surfaces. →If H is the height of slip gauge combination and L is the center distance between two rollers. Then,           Sin θ =  (h / L).                θ = sin^-1 (h / L).             θ = Slope of object su
