Enter the total ballast (lbs) and the total displacement (lbs) into the Calculator. The calculator will evaluate the Ballast Displacement Ratio. 

Ballast Displacement Ratio Formula

BDR = B / D

Variables:

  • BDR is the Ballast Displacement Ratio (lbs/lbs)
  • B is the total ballast (lbs)
  • D is the total displacement (lbs)

To calculate the Ballast Displacement Ratio, divide the total ballast by the total displacement.

How to Calculate Ballast Displacement Ratio?

The following steps outline how to calculate the Ballast Displacement Ratio.

  1. First, determine the total ballast (lbs). 
  2. Next, determine the total displacement (lbs). 
  3. Next, gather the formula from above = BDR = B / D.
  4. Finally, calculate the Ballast Displacement Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total ballast (lbs) = 5000

total displacement (lbs) = 1000
