How to calculate feet of head pool pump

How do you calculate pump head?

To calculate Total Dynamic Head, also known as TDH, we need to calculate two things: A) The Vertical Rise. B) The Friction Losses of all the pipe and components the liquid encounters on the discharge of the pump.19 мая 2016 г.

What is feet of head on a 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.

How do I calculate the flow rate of my pool pump?

Divide the pool gallonage by the turnover rate to determine the minimum flow rate per hour. Divide that number by 60 to determine the minimum flow rate per minute.

How do you calculate total dynamic head in feet of water?

Total dynamic head = elevation head + friction head loss + pressure head. A. Elevation head – is the vertical distance which the water must be pumped. It is the elevation difference in feet between the pumping level in the well and the pressure tank.

How do I calculate flow rate?

The flow rate formula, in general, is Q = A × v, where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point.

What is head height pump?

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

How do you convert pump head to 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.

What does total head in feet mean?

Total Dynamic Head (TDH) refers to the total equivalent height that a fluid will be pumped by taking into consideration any friction losses in the pipe. … The total sum of the pipes’ lengths, rise in elevation and addition of 45-degree /90-degree turns will affect the feet of head number.

How many hours a day should a pool pump run?

8 hours

Should I run my pool pump at night or day?

It may be cheaper to run the pump at night, but honestly you should run it 1 hour a day per 10 degrees of temperature at least, and it should be during the day. Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up.
