### Diode in Reverse Bias and Breakdown | Electronics Device and Circuits | EC

Monday, 18 September 2017

Real Life Applications: We all are using voltage reference circuits (Voltage regulators) in real life. This is because of breakdown in diodes and some time it will exceed maximum power handling capacity of the device then it will burn out. So it is important to see exactly what is happening inside the device. Explanation: Diode

### Limit State Method Of Design | Reinforced Cement Concrete | CE

Monday, 18 September 2017

Working Stress Method: The stresses in the member is obtained from the working loads and compared with permissible stresses. Working Stress method will lead to large FOS and over-sized sections, thus the sections will be uneconomical. WSM is still being used in special structures such as water tanks, bridges, chimneys in India. Ultimate Load Method:

### Frequency analysis of Rainfall/Flood data | Hydrology | CE

Tuesday, 12 September 2017

Real Life Application Frequency analysis plays an important role in hydraulic engineering applications such as those concerned with floods, for example in construction of Dams it is necessary to find out the probability of occurring an extreme flood. Explanation To understand the concept with clarity it’s important to understand two things:- 1. Probability 2. Return

### Sedimentation | Environmental Engineering | CE

Tuesday, 12 September 2017

Real Life Application A concept used in the treatment of raw water before supplying the water to a city or a town. This is adopted for surface water where water has high concentration of finer suspended impurities and is one of the most important treatment given to raw water in a water supply treatment plant.

### Load Life Relationship of Rolling Contact Bearing | Machine Design | ME

Tuesday, 12 September 2017

Real Life Application Whenever we purchase a bearing, expected life is given by the manufacturer for a particular value of load but we need to know the expected life of the bearing for the load it is going to experience in that application. The load life relationship serves this purpose. Explanation To find out the

### Even and Odd Signals | Signals and Systems | EC

Tuesday, 12 September 2017

Real Life Applications: Symmetry is an important property in Signals. Even in nature, it is observed that symmetry plays an important role whether it is a human body or plants around us. It also adds an aesthetic sense to it. It can help to reduce computations and therefore reduce the delay in processing. Its a

### Analysis of 3 Phase Induction Motor | Electrical Machines | EE

Tuesday, 12 September 2017

Real Life Application A 3 phase induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An

### Unconventional Machining Processes

Wednesday, 30 August 2017

Real Life Application- Due to the innovative nature and numerous material and machining benefits of pECM, the technology finds very wide cross-industry application. To current date, ECM Technologies have researched and developed for the majority of the high industries. It is normally used for mass production and is used for working extremely hard materials or

### NPSH (Net Positive Suction Head)

Saturday, 12 August 2017

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?

Thursday, 20 July 2017

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
