Difference between Heat and Temperature

2023-02-09T13:08:00.002+05:30

In simple words, Heat is the Energy and the temperature is the driving force for transfer of heat.

According to the Law of conservation of Energy:

"The law of conservation of energy states that the amount of energy is neither created nor destroyed." But, one form of energy can be converted to another form.

The temperature difference at the two ends, is the cause of the transfer of the heat from the Hot end towards the cold end.

examples from day to life:

a) The heat energy is supplied to the surface of a vessel which uses the temperature difference and absorbs the energy introduced to raise the temperature of the vessel.

b) When an iron rod is heated at end, heat is generated at the tip closest to the flame. But the heat is transferred from the hot end to the cold end slowly due to the nature of the metal to distribute the energy towards the colder end and reach an equilibrium state.

c) In gases the heat is generated due to the randomness created among the molecules of the gases which is also called entropy. In general, the with the supply of heat the gases tend to mover faster due to excitation. When they hit a surface, which is in their way of movement, then ten to lose the energy absorbed and eventually heating the surface of the vessel or object. (and many a time exerting more pressure on the surface of the vessel).

SCADA: The automation tool

2020-08-10T17:46:00.001+05:30

Supervisory Control and Data acquisition is a platform where the equipment and the interface machines are monitored with their activities of operations. This system helps in monitoring the actual operations without the involvement of manual existence and data collection. The data is acquired and is stored in a systematic date tagged for informing the activity observations which occur in its continuous operations.

This technology has evolved into a very useful platform in monitoring the data an simulations and relevant data and information where you have numerous tagged entities performing their individual tasks.

This tool has a Human Machine Interface, where the monitoring of the data can be done. Usually, the data is transferred with the help of the Remote Transmission Units ( RTU). The data is deposited to the monitoring stations at backup storage which can be motivated to have control over the functions of the machines. The technology can be interfaced with the Radio frequencies as well which can produce efficient control with its own dedicated frequency band for operation with least disturbance.

SCADA systems can play the role of supervision and also can be modified into a control platform where the individual machine element can be sent feedback for its operations. Error and malfunctioning details can be easily accumulated at later stages it can analyze the data and finally reach an automation stage responding to various small interpretations reducing the human involvement in resolving such adjustments. This technological platform is already in use in industries related to energy, oil and gas water, and so on.

There are a few limitations that have been seen in the case of security of the units in data access which is normally optimized by introducing a strong firewall setup.

We hope, this was helpful in understanding the basics and the fundamental working of the SCADA based automation systems. Please feel free to drop a comment for any query you happen to face.

We'll try our best to reach your answers satisfactorily.

Force is an external agency that acts on an object directly or indirectly causing a change in its state.

The force can cause the object to move from one place to another by just inducing the movement to a body at rest. In a simple physical explanation we can ask a player standing at the end of the second post to kick the ball in when the ball approaches him in the direction of the goal post.

In this example the boy is asked to change the course/ direction of the football by inducing a simple push in the desired direction to celebrate a goal. But before this let us consider that the situation was of a corner where this earlier scenario is to follow the heavy push on the ball from the corner of the ground. Here there is a need to push the ball with the might onto the surface of the ball which will cause the impact on the ball. on a whole the ball will fly with the intensity of the force which was imposed onto it. But wait a minute just let's slow this hit down in terms of speed at which it happened. There you go.
There is the first law of motion acting on the object finally producing its way to the second law of motion.
The ball changed it shape initially with the stationary opposite untouched part of the ball. Heyy!!! the ball has changed its shape....or let's put it in this way... The force happened to change the ball. But see the ball gained its speed.
What exactly happened? The inflated ball's air got push in the desired direction finally pushing it in that direction that's intentional in this case. The ball reached the man on the second pole but let's see carefully the goalkeeper's hands are visible here. He humps and simple takes the ball to the fists of his the ball changed its direction again flying away.

The goalkeeper saved the day. And not everything is out of control in life. You can always try saving the undone and always try to flick the goal. It's all in the force you bear within.

Ignition...... with a Spark Plug

2019-12-19T13:19:00.000+05:30

Ignition is the process of initiation of combustion in the presence of fuel to burn.

What are the basic components required to have the ignition? to have an explosion, to burn the fuels, to have all around you to get lit........... I wonder its the fuel and more importantly a spark in there to start the process to get going.

This is a rather usual word that we find in our daily motivative life... oHHk let's get back to our motive here the automotive.

The ignition in an automotive of the PETROL vehicle is all with the help of a tiny spark caused in the electrodes in the spark plug which usually has a gap of 0.6 to 0.7 mm gap.

This happens in a very controlled environment which is the combustion chamber i.e. the cylinder where the injection of fuel and the burning and the removal of exhaust all takes place one after another completing the four strokes of the combustion process in such engines.

The engine here is a assembled structure of various parts that together will make the resulting output source at the output shaft providing the BHP (Brake Horse Power) that produces the final power that can be used for the production of the final drive towards the wheel's axle.

So, let's just stick to this new spark for now. And here's a platform to produce your creative skills producing the models of the spark plugs.

We'll be more into this and you can follow us for more details in this subject as we've just kicked the rod to begin the wave-front.
