Nozzles & Diffusers simple explanation. By Yuvi - Study Point

Hey everyone, so today we are going to learn about Nozzles and Diffusers in a simple or easy way.
So, without wasting much time lets get started.

NOZZLE
  • Nozzle converts the pressure energy into kinetic energy and Diffuser is just reverse of Nozzle as it converts kinetic energy into pressure energy.
  • The nozzle can be convergent and can be divergent and it has a varying cross-section.
  • And we can say that it's main purpose is to obtain kinetic energy means at the expense of pressure energy we obtain pressure energy.
  • And this high-velocity jet which emerges from the nozzle is used for many purposes or a variety of purposes.
Where are nozzles used?

 ~ it is used in gas turbines, hydro turbines & steam turbines.
  • And the Nozzle's mass flow rate throughout the passage remains constant.
  • The high-velocity jet which is coming out of the nozzle hits the turbine blades and due to this, the rotor starts rotating in a particular direction. 
  • And because of this high grid energy is produced means the pressure energy generates the kinetic energy.
  • Three types of Nozzles are their converging nozzle, diverging nozzle, convergent and divergent nozzle.
[Which is further briefly explained in this lecture video in a very simple or easy way. So, please go and check out this video.]
Diffuser
  • As I have told you in starting that Diffusers converts the kinetic energy into pressure energy. Which means it is reverse of the Nozzle.
Where are diffusers used?

 ~ centrifugal pump it converts the kinetic energy of the fluid into pressure energy.

Impulse turbine simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to understand about Impulse turbine. So, without wasting any time lets get started. In an impulse turbine, we are generating power by making the use of high-speed water jet impact. once, we have high-speed water jet, we can use its impact to rotate a turbine. In impulse turbine potential energy of the water is converted into kinetic energy by passing it through a nozzle. Impulse turbine is totally remain dipped in water. We can say that the impulse turbine uses Newton's second law of motion as it totally depends on two main factors i.e, the mass of water which was flowing into the turbine and change in the velocity of the flow coming into the turbine to that of going out of turbine after impact.                                 As with a considerable decrement in the velocity, the mass of water entering into the turbine is same as that of mass coming out of t...

NBFM & WBFM (Narrow band frequency modulation & Wide band frequency modulation) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to learn about NBFM & WBFM (Narrowband frequency modulation & Wideband frequency modulation) in simple or easy way. So, without wasting any time lets get started. The information about NBFM & WBFM When the spectrum's efficiency is important or it is required then we use NBFM (Narrowband frequency modulation) is used.  But when better signal quality is required or when it is important then we use WBFM (Wideband frequency modulation). The term NBFM is used for those applications where the modulation index is less than or equal to 1. And the term WBFM is used for those applications where the modulation index is greater than or equal to 1. Now, let's see more difference between Narrow band frequency modulation(NBFM) and Wideband frequency modulation(WBFM). The term narrow-band and wide-band refer to the actual radio channel bandwidth. The purpose or advantage of using NBFM (Narrowband frequency modulation) The purpo...

Ohm's law simple learning BY Yuvi - Study Point

Hey guys, have you ever heard about Ohm's law, ok so I will teach you in an easy way. So let's get started. It is the basic rule of electricity and it explains the relationship between voltage, electric current & resistance. Ohm's law states that the electric current which is flowing through a circuit or conductor is directly proportional to the voltage and inversely proportional to the resistance. In other words, if resistance is not changed then the electric current flowing through a conductor will increase with the increase in voltage. And if the voltage is not changed then the electric current which is flowing through a conductor decreases with the increase in resistance.    Ohm's law formulas, V = I * R R = V / I I = V / R Ohm's law states that Resistance (R) of the conductor is constant. [*Note = But research shows that the resistance is directly proportional to the length of the conductor and inversely proportional to the cross-sec...
