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.
