How do you find the minimum thickness?

How to Calculate Minimum Wall Thickness

  1. Determine the maximum pressure that the pipe will endure.
  2. Determine the allowable stress of the wall material.
  3. If you already have a pipe to work with, use calipers to measure it.
  4. Multiply the outside diameter in inches by the pressure in psi by 1/2.
  5. Divide the result of Step 4 by the allowable stress.

How do you calculate thickness?

We obtain the thickness of the solid by dividing its volume by its length and its width; that is, we divide 24 cm3 by 4 cm and 3 cm. In this example, the thickness of the solid is 2 cm. Example Exercise 3.10 further illustrates finding the thickness of rectangular solid.

How do you find the minimum thickness of a plate?

Solving for Minimum Thickness of a Force Plate

  1. Formulate. The average force plate is composed of AISI stainless steel 304, which has a modulus of elasticity of 193 x 10^3 MPa and a Poisson’s ratio of 0.29 [3].
  2. Solve. Solve for maximum stress applied to plate: σ = F/A = 5000 N / (0.4064 m x 0.6096 m)
  3. References. [1] Bertec. (
