Chetankumar replied | 12/04/2016

There are two types
1. flat belt drive
2. compound belt drive
and these two are further classified

Shalabh replied | 27/06/2016

Belts drives are classified as

Ravi Siwach replied | 19/04/2016

Adiabatic process is that in which there is no transfer of heat between between system and surrounding dQ=0.
But in polytropic process heat transfer takes place reversibly and it follows eqn.
PVraise to power n =contant.
PVn= constant

Kshitij replied | 29/06/2016

Adiabatic change is the one in which no heat is transferred into or out of the system. Heat transfer can be mainly stopped by two ways. One is by using a thermally insulated boundary, so that no heat can enter or exist.In thermodynamics, adiabatic changes are shown by dQ=0.

Venkateshkumar replied | 18/03/2016

Ampere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.

V replied | 19/03/2016

it is a work law of a magnetic field , amperes's law states that the line integral of magnetic field intensity(H) around any closed path equal to direct current enclosed by the path it is analogs to gauss's law in electric fields

What is Gauss law?

M replied | 16/03/2016

The Gauss' Law is used to find electric field when the charge is continuously distributed within an object with symmetrical geometry, such as sphere, cylinder, or plane. Gauss' law follows Coulomb's law and the Superposition Principle.

Hsa Tuition Academy replied | 16/03/2016

The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.

The main advantage of a MOSFET over a regular transistor is that it requires very little current to turn on (less than 1mA), while delivering a much higher current to a load (10 to 50A or more).

S.shekar replied | 13/05/2016

to avoid the effect of hammering of water on the inner surface of pipes other wise the pipe will burst if flowing water is stopped immedietly. this is controlled by surge tank by which we can control the pressure of liquids in pipes. shortly we can say to avoid hammering effect of water or liquids.

Rohit replied | 21/05/2016

We provide a surge tank because, just in case if someone suddenly closes the outlet valve while the water is flowing through the pipe, it will produce an effect knon as water hammer which will destroy the pipe. If a surge tank is there then the water will go and rise in surge tank Ra ty her than producing water hammer. It's a kind of fail safe system.

Girish replied | 15/03/2016

when physical state of conductor remain same then current flowing through the conductor will be directly proportional to the potential different applied across it. But understand one thing this law is strictly applicable to the devices which follows linear characteristics.

Vikash Lomash replied | 16/06/2016

Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.
