### Stream Function – 1 | Fluid Mechanics | ME/ CE

Wednesday, 15 November 2017

Real Life Application Stream function is a mathematical postulation with scalar characteristics, defined for flow fields of incompressible fluids. This function helps to describe the flow velocity components and thus plot streamlines and path lines which represent the trajectories of fluid particles. Explanation Mathematically the stream function for a flow field can be evaluated from

### Analysis of Trusses – Zero Force Members | Engineering Mechanics | ME/ CE

Wednesday, 15 November 2017

Real Life Application For everyday occurrence, trusses are incorporated into numerous structures all around us, though we probably rarely notice. Here are just a few examples: 1.Bridges – Arch bridges, suspension bridges, cantilevered bridges. 2. Roofing – Practically all modern domestic housing, both timber and steel, employs trusses to span ceilings and support the roof

### Layout of Wastewater Engineering | Environmental Engineering | CE

Wednesday, 15 November 2017

Real Life Application A study of management of wastewater produced from a city. It involves the transportation of wastewater from various parts of the city to a wastewater treatment plant, where it the concentration of effluents are reduced so that it can be safely disposed in a source. Explanation The wastewater generated from a city

### Velocity Analysis of slider crank mechanism | Kinematics of Machinery | ME

Friday, 20 October 2017

Real Life Application: Velocity analysis is prerequisite for acceleration analysis which further leads to force analysis which is the base for design of any machine element. Velocity Analysis: By velocity analysis we determine the velocity characteristics (linear and angular) of all links of a mechanism at a given configuration, when the input velocity is specified.

### Infiltration Index | Hydrology | CE

Friday, 20 October 2017

Real Life Application To find out net amount of rain it is required to analyses the amount of losses. Infiltration is a loss to us when net rainfall is concerned. As a water resource engineer it is important for us to know the amount of losses so that to know the amount of rain which

### Junction Field Effect | Electronic devices | EC

Friday, 20 October 2017

Real Life Application: In saturation region JFET will act as an amplifier. Input impedance offered by this device is very high so we can use as input component of voltage amplifier. Packing density is higher than BJTs. Explanation: Source: Terminal which will provide majority charge carrier to device is known as Source. Drain: Terminal which

### Direct and indirect bandgap material | Electronic devices | EC

Friday, 20 October 2017

Real life application: In daily life we are using semiconductor devices. LED are one of them whom we are using in TV remote, traffic signals etc. The materials required to make those devices are direct band gap material.   Explanation: Indirect Band gap material: During recombination if electron from conduction band is not coming to

### Stress | Strength of Materials | ME/CE

Friday, 20 October 2017

Real Life Applications: Whenever a load is applied on a deformable solid, to find out whether the load will cause failure or not is decided by stress. Strength of the material is the stress the material can take up to failure. To understand the strength of the material concept of stress should be clear Explanantion:

### Raw Water | Environmental Engineering | CE

Friday, 20 October 2017

Real Life Application A study of water supply system, starting from the intake of the water from a source and then caring out the necessary treatment for the purification of the water so that it is safe for potable purpose and can be supplied to a city. Explanation The raw water engineering involves the determination
