Pressure head

Ok, kiddo, so let's say you have a big bucket of water and you want to make it flow through a pipe like water flows through a straw. But the water won't just start moving on its own - you need to do something to make it move, like blowing air into the straw to make the water come out the other end.

The thing that makes the water move through the pipe is something called pressure. Pressure is like a big, invisible force that makes things happen - kind of like how your mom or dad can make you do things even if you don't really want to!

So pressure head is like the power of the pressure that's pushing the water through the pipe. Imagine that the pressure has a head on top of it, like a little hat or crown, and the height of that head is how much power the pressure has. The higher the head, the more powerful the pressure, and the faster the water will flow through the pipe.

So if you want to make the water flow faster through the pipe, you need to either add more water to the bucket or increase the pressure head by doing something like blowing more air into the straw. Hopefully that helps you understand pressure head a little better!
