## How do you calculate pool TDH?

CALCULATE TDH – Multiple the Vacuum gauge reading x 1.13. Multiply the Pressure gauge reading x 2.31. Add the two products together to determine TDH for your system. Our readings were 15 and 23 respectively So (15 x 1.13) + (23 x 2.31) = 17 + 53 or 70 TDH.

### How do I calculate Head feet of a pool?

The operating point for any pump is where the pump curve intersects with the system curve. Your pressure can be converted into feet of head by multiplying by 2.31. 12 x 2.31 = 27.7 feet of head for the pressure side.

#### How do you calculate pool volume?

For a rectangular pool, multiply the length times the width, then multiply by the average depth. Finally, multiply by 7.5. For example, a pool that’s 30 feet in length and 15 feet wide, with an average depth of 5 feet, would be 30 x 15 x 5 x 7.5= 16,875.

**How do I know what size pool pump I need?**

Determine how many gallons you need to pump per hour to clean all the water in your pool in eight hours. Divide the gallons of water your pool holds (answer from step 1) by eight. Using the example number of gallons previously given, this equation would look as follows: 24,000 gallons ÷ 8 hours = 3,000.

**What is TDH for pool pump?**

Total Dynamic Head (TDH) is crucial when choosing the appropriate pump size for a swimming pool. TDH is the measurement of the total resistance of the water flow moving through the pool system.

## What is TDH in water?

When a pump is lifting or pumping water, the vertical distance (in feet or meters) from the elevation of the energy grade line on the suction side of the pump to the elevation of the energy grade line on the discharge side of the pump.

### What is TDH in pool pumps?

#### How many gallons is a 18×36 pool?

Standard In-Ground Pool Volumes in Gallons by Size | ||
---|---|---|

16×32 | 13,400 | 15,400 |

18×36 | 17,000 | 19,400 |

19×38 | 19,000 | 21,700 |

20×40 | 21,000 | 24,000 |

**What is TDH ft water?**

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. Essentially “dynamic head” is the measurement of resistance working against your pool pump as it pulls water from your basin and pushes it back to the pool.

**What is the pump TDH?**

## What is the unit of TDH?

TDH is also the work done by the pump per unit weight, per unit volume of fluid.

### What is Max total head ft?

Max Head refers to a pump’s capability to push water upwards (also known as ‘vertical lift’). So for example, a pump which states ‘Max Head: 7m’ means the pump will be able to push water flow up to 7 metres high from the water surface.

#### How many Btus do I need for a 30000 gallon pool?

120K BTU

Pools up to 30,000 gallons should look at the AquaCal 120K BTU or higher, and 40,000 gallon inground pools should look at models like the Pentair 140K BTU.
