Valve Spring Pressure Formula
The following formula is used to calculate the Valve Spring Pressure.
Pvalve = K / L
- Where Pvalve is the Valve Spring Pressure (N/m^2)
- K is the spring rate (N/m)
- L is the total lift (m)
How to Calculate Valve Spring Pressure?
The following two example problems outline how to calculate the Valve Spring Pressure.
Example Problem #1:
- First, determine the spring rate (N/m). In this example, the spring rate (N/m) is given as 100.
- Next, determine the total lift (m). For this problem, the total lift (m) is given as 5.
- Finally, calculate the Valve Spring Pressure using the equation above:
Pvalve = K / L
Inserting the values from above and solving the equation:
Pvalve =100 / 5 = 20 (N/m^2)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
spring rate (N/m) = 200
total lift (m) = .8
Entering these values yields:
Pvalve = 200/ .8 = 250 (N/m^2)
