What is pump head in fluid mechanics?

Head is the height at which a pump can raise water up, that’s it, it’s that simple. Figure 2 The meaning of head. Connect a tube to the discharge of a pump and measure the water height, that the head of the pump.

What is head in pump selection?

Put simply, head is the height at which a pump can raise fluid up and is measured in metres or feet.

What is head in centrifugal pump?

Head—Resistance to Flow In Newtonian (true) fluids (non-viscous liquids, such as water or gasoline), the term head is the measurement of the kinetic energy that a centrifugal pump creates. Imagine a pipe shooting a jet of water straight into the air. The height that the water reaches is the head.

What is section head in pump?

The pump head or discharge head of a water pump is a measure of the power of a pump. This statistic is measured in meters (or feet) and is calculated by placing a tube on a pump’s discharge and measuring the maximum height to which it can pump water.

What is a system head?

A system head curve is a common type of tool used in pump selection and system design and sizing. It combines elements of the performance (H-Q) curve of the specific pump under consideration with the combined static, operating, and frictional loss heads (the total dynamic head or TDH) of the system under design.

What is difference between head and pressure?

By definition, ‘Head’ is a measure of energy. The units of energy are feet (or meters). ‘Pressure’ is a force applied against a unit of area such as a pound of force applied to a square inch of area (psi). The density is a component of pressure.

What is the difference between head and pressure?

By definition, ‘Head’ is a measure of energy. The units of energy are feet (or meters). ‘Pressure’ is a force applied against a unit of area such as a pound of force applied to a square inch of area (psi). The liquid’s density determines the force.

How is head of system calculated?

How do you calculate pump head in a closed system?

So, for hydronic applications, we can say that: For closed systems: Pump head = the sum of all friction pressure drops Where: Friction pressure drop = piping pressure drop + terminal unit pressure drop + source unit pressure drop* + valve pressure drop + accessories pressure drop.

What does pump head pressure mean?

Head pressure is a specific type of pressure used in pump systems. It is a measurement of the height difference between the fluid being moved and the discharge point. For example, let’s say you have a well of water that is 2 metres underground, and you have a tap and pipe system half a metre above ground.

What is the relation between head and pressure?

In simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.
