## What is the head of water?

“Head” in fluid dynamics In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid.

…

Head is expressed in units of height such as meters or feet.

The static head of a pump is the maximum height (pressure) it can deliver..

## How do you calculate water flow rate?

If the liquid is flowing through a pipe, the area is A = πr2, where r is the radius of the pipe. For a rectangle, the area is A = wh where w is the width, and h is the height. The flow rate can be measured in meters cubed per second (m3/s), or in liters per second (L/s).

## Why do I feel my head heavy?

There are many different possible causes of a head that feels heavy. These range from mild conditions like a headache or sinus infection, to more serious conditions like a concussion or brain tumor. Most often, a head that feels heavy isn’t serious.

## What is head rise?

Actual Head Rise of a Pump or Fan Using the Energy Equation the head rise through a pump or fan can be expressed as: ha = (p2 – p1) / γ + (h2 – h1) + (v22 – v12) / 2 g (1) where. ha = actual head rise (m fluid column) p = pressure (Pa, N/m2)

## What is mental method?
