For students, it is just a topic but it is a key term for pump manufacturers. First of all, let’s discuss that how a pump works. Pumps operate by creating low pressure at the inlet which allows the liquid to be pushed into the pump by atmospheric or head pressure. Even with a perfect vacuum

What Entropy indicates?

Second law of thermodynamics leads to the birth of a new property i.e. entropy which is an abstract property. Entropy is a very useful property, we all know but why the word entropy is not used in daily life like other properties (Energy, temperature and pressure). Answer of this question is that we don’t understand

Flywheel and Governor are used to control the speed fluctuations of an internal combustion engine. But these fluctuations take place in two ways: 1) During a cycle (due to variation of torque on the crankshaft) 2) Over a no of cycle (due to the variation of load on the engine) In first case, speed fluctuations

Real Life Application The application of magnetizing curve of non-linear core in transformers is very important in the design of the transformer connection, wherever a transformer is to be installed. The induced emf, the load current, the source current, the magnetic flux waveforms depend on the type of connection in the transformer. For example: 1

Real Life Application This is an extremely useful and beautiful part of mathematics and forms the basis of many techniques employed in many branches of mathematics and physics. In fact, to a large extent complex analysis is the study of analytic functions. Explanation The function f(z) which is single valued is analytic in a domain

Application Concept of convolution has wide ranging applications such as its usage in digital image processing for the purpose of filtering, improving certain features of images and many other signal processing applications. Explanation Convolution is a mathematical operator which relates input and output of an LTI system. It is only with the help of convolution

Real Life Application Autotransformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example 132 kV to 66 kV for transmission. Another application in industry is to adapt machinery built (for example) for 480 V supplies to operate on a 600 V supply. They are also often used for

Real Life Application The application of Phasor connection of Three Phase transformers is very important in the transmission and distribution of Power. It is the three phase system which has been adopted world over to generate, transmit and distribute electrical power. Therefore to change the level of voltages in the system three phase transformers should

Real Life Application This concept finds application in data transmission and reception in TV signals, internet and various signal processing applications. Ultra slow motion is one application area of time scaling operation. Explanation Transformation on Independent Variable (time) is a very important concept in Signals and Systems. It finds its application in Convolution, Periodic signals,

Application Special matrices based on symmetry find their application in mathematical analysis. Eigen Values and Eigen vectors of special matrices display some important properties. Explanation To understand this concept, knowledge of matrix representation and transpose is required. Symmetric Matrix: Transpose of a square matrix is equal to matrix itself. Skew Symmetric Matrix: Transpose of a
