Click ‘Get Form’ to open the tdh calculation worksheet in the editor.
Begin by calculating the pool volume. Enter the surface area and average depth in the designated fields, then multiply these values by 7.48 to find the total volume in gallons.
Next, determine your preferred turnover time. Input the hours into the appropriate field and convert this into minutes by multiplying by 60.
For maximum pool flow rate, divide the gallons by turnover time in minutes. Add any water feature flow rates as needed for accurate calculations.
Fill in the branch, trunk, and return piping sizes to maintain proper velocity at specified gpm rates.
Calculate simplified TDH by entering lengths of return and suction pipes along with their respective head per foot values.
Finally, sum up all losses from filters and heaters to get your total simplified TDH for pump selection.

In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid. TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
What is the TDH capacity of a pump?
3:42 5:46 Then well take the 13 ft. And add it to our 10 ft of vertical. Head our TDH would be about 23 ft.MoreThen well take the 13 ft. And add it to our 10 ft of vertical. Head our TDH would be about 23 ft.
What is the formula for calculating total pressure?
Think of TDH as the pumps total lifting capacity. It accounts for all the resistance the pump needs to overcome to effectively move the liquid from its source to its destination. Imagine climbing a hill while carrying water; the higher the hill and the heavier the water, the more effort you need.
What is TDH measured in?
Ptotal = P1 + P2 + P3 + .. 1)Use PV = nRT to calculate the individual pressure of each gas in a mixture. 2)Use the mole fraction of each gas to calculate the percentage of pressure from the total pressure asdocHub to each individual gas.
