Hi, Professor Vishal Della, welcome to my YouTube channels.
In this video, I teach you head of centrifugal pumps.
So that is a different type of head that we discuss in this video.
Before that, I first discuss you what is a head.
Head means that is a difference between the height.
Okay.
It is known as the head.
So that is a different type of head that is a suction head, delivery head, static head
and nanometric heads.
So, we discussed that in details with its equations.
So, it is a centrifugal pump, this is a suction pipe and this is the delivery pipes.
If you don't know this construction and working of centrifugal pump, then I request
to go to the playlist and also from in the description, there is video link is available
and also from the i symbol, you can watch this video of a pump.
So, what is a suction head?
Suction head is denoted as the HS.
H means head and S is written for suction.
It is the vertical height of the free surface of liquid in a sump to the center of the pump.
This is the free surface of water in a sump and this is the center part of the sump.
So this height is denoted as the HS.
So here I draw one rectangle.
Okay, this is the surface of water and this is the center.
So this height is measured in a meter and it is denoted as the HS.
Next is the delivery head.
It is denoted as the HD, D for delivery and H for H.
So it is a vertical distance between the center of this pump, this is the center of pump to
the water surface in the tank.
This is a tank and this is the water surface in the tank, where the liquid may be delivered.
So here it is indicated as the HD from the center point to this water level in this tank,
it is denoted as the HD means delivery head.
Next term is the static head.
The static head is also denoted as the HS.
But for a static head, H is written as the capital.
So, it is also denoted as HS.
Static head is the sum of suction head and the delivery head.
Means capital HS is equal to HS plus HD.
So, here you see the, it is the HS and HD.
So, again I draw the one line that is indicating the summation of hs plus hd.
So, from this water level that means water level in a sump to the water level in the
tank it is known as the static head hs.
Next is the manometric head.
Before that I request to like the video and comment on the video.
The manometric head it is denoted as the hm.
H is head, M is nanometric. It is the head against which centrifugal pump has to work.
also known as that actual water delivered by the pump it is known as the manometric
head.
So, manometric head is find by using the three different methods that we discuss.
So, first is that manometric head is the sum of static head this capital Hs and all the
head losses again which the pump has to work expect the kinetic head.
So, where is the various what various losses.
