- Click ‘Get Form’ to open the Total Dynamic Head Calculation Worksheet in the editor.
- Begin by calculating the Pool Volume. Input the Surface Area and Average Depth in the designated fields, then multiply these values by 7.48 to convert cubic feet to gallons.
- Next, determine your preferred Turnover Time in hours. Enter this value and multiply it by 60 to convert it into minutes for further calculations.
- Calculate the Maximum Flow Rate by dividing the Pool Volume (in gallons) by the Turnover Time (in minutes). Fill in each field accurately for precise results.
- For Spa Jets, input the number of jets and their flow rate per jet to find the total jet flow rate.
- Finally, assess pipe sizes based on maximum system flow rates and ensure all friction losses are accounted for in your TDH calculations.
