PTO Ratio Formula
The following formula is used to calculate the PTO Ratio.
PTOR = EQ / ES
- Where PTOR is the PTO Ratio
- EQ is the equipment speed (RPM)
- ES is the engine speed (RPM)
To calculate a PTO ratio, divide the equipment speed by the engine speed.
How to Calculate PTO Ratio?
The following example problems outline how to calculate PTO Ratio.
Example Problem #1:
- First, determine the equipment speed (RPM).
- The equipment speed (RPM) is given as: 500.
- Next, determine the engine speed (RPM).
- The engine speed (RPM) is provided as: 8000.
- Finally, calculate the PTO Ratio using the equation above:
PTOR = EQ / ES * 100
The values given above are inserted into the equation below and the solution is calculated:
PTOR = 500 / 8000 * 100 = 6.25 (%)
Example Problem #2:
For this problem, the variables required are provided below:
equipment speed (RPM) = 600
engine speed (RPM) = 1000
Test your knowledge using the equation and check your answer with the calculator above.
PTOR = EQ / ES * 100 = ?
