Spade Thickness Formula
The following formula is used to calculate the Spade Thickness.
ST = P*D / (2*F*S)
Variables:
- ST is the Spade Thickness (mm)
- P is the design pressure (kPa)
- D is the outside diameter (mm)
- F is the design factor
- S is the yield strength (kPa)
To calculate the spade thickness, multiply the design pressure by the outside diameter, then divide by the product of 2 times the design factor times the yield strength.
How to Calculate Spade Thickness?
The following steps outline how to calculate the Spade Thickness.
- First, determine the design pressure (kPa).
- Next, determine the outside diameter (mm).
- Next, determine the design factor.
- Next, gather the formula from above = ST = P*D / (2*F*S).
- Finally, calculate the Spade Thickness.
- 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.
design pressure (kPa) = 7900
outside diameter (mm) = 250
design factor = .89
ST = P*D / (2*F*S) = ?
