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?
The mental method is the process of working out maths calculations and carrying out problem-solving mentally, without the need to write down any working out. Mental calculations involve using specific techniques for solving specific types of problems rather than memorizing the answers to equations.
