E/One Grinder Pump Station Ballast Calculations

Sample Calculation, DH272/DR272

C. Subtract the buoyant force from the ballast force to determine the final condition

Final Condition

= Ballast Force - Buoyant Force

= 5973.0 lb – 2165.4 lb

=

3807.6

lb

The approach outlined above may be used to calculate the ballast requirements listed below.
