The image above represents turbine stiffness. To calculate turbine stiffness (correction factor), two essential parameters are needed, and these parameters are the Correction Factor for Radius of Curvature with Deflection (c) and Parallel Plate Stiffness for Tubing (σp).

The formula for calculating turbine stiffness:

σ = 0.149c[σ_p]

Where:

σ = Turbine Stiffness
c = Correction Factor for Radius of Curvature with Deflection
σ_p = Parallel Plate Stiffness for Tubing

Let’s solve an example;
Find the turbine stiffness when the correction factor for radius of curvature with deflection is 15 and the parallel plate stiffness for tubing is 3.

This implies that;

c = Correction Factor for Radius of Curvature with Deflection = 15
σ_p = Parallel Plate Stiffness for Tubing = 3

σ = 0.149c[σ_p]
That is, σ = 0.149(15)[3]
σ = 6.705

Therefore, the turbine stiffness is 6.705.

Calculating for the Correction Factor for Radius of Curvature with Deflection when the Turbine Stiffness and the Parallel Plate Stiffness for Tubing are Given

c = ^σ / _{0.149 x σ_p}

Where;

c = Correction Factor for Radius of Curvature with Deflection
σ = Turbine Stiffness
σ_p = Parallel Plate Stiffness for Tubing

Let’s solve an example;
Find the correction factor for radius of curvature with deflection when the turbine stiffness is 32 and the parallel plate stiffness for tubing is 8.

This implies that;

σ = Turbine Stiffness = 32
σ_p = Parallel Plate Stiffness for Tubing = 8

c = ^σ / _{0.149 x σ_p}
So, c = ³² / _{0.149 x 8}
c = ³² / _1.192
c = 26.84

Therefore, the correction factor for radius of curvature with deflection is 26.84.

Calculating for the Parallel Plate Stiffness for Tubing when the Turbine Stiffness and the Correction Factor for Radius of Curvature with Deflection are Given

σ_p = ^σ / _{0.149 x c}

Where;

σ_p = Parallel Plate Stiffness for Tubing
σ = Turbine Stiffness
c = Correction Factor for Radius of Curvature with Deflection

Let’s solve an example;
Find the parallel plate stiffness for tubing when turbine stiffness is 40 and the correction factor for radius of curvature with deflection is 6.

This implies that;

σ = Turbine Stiffness = 40
c = Correction Factor for Radius of Curvature with Deflection = 6

σ_p = ^σ / _{0.149 x c}
That is, σ_p = ⁴⁰ / _{0.149 x 6}
σ_p = ⁴⁰ / _0.894
σ_p = 44.74

Therefore, the parallel plate stiffness for tubing is 44.74.
