Solve the Colebrook equation: 1/√f = −2 log(ε/(3.7D) + 2.51/(Re√f)). Or use the explicit Swamee-Jain formula: f = 0.25/[log(ε/(3.7D) + 5.74/Re^0.9)]² for turbulent flow.
2D stress state at a point. All stresses in MPa.
Enter the values for the patient or scenario you are assessing. Solve the Colebrook equation: 1/√f = −2 log(ε/(3.7D) + 2.51/(Re√f)). Or use the explicit Swamee-Jain formula: f = 0.25/[log(ε/(3.7D) + 5.74/Re^0.9)]² for turbulent flow. Use the moody friction factor result to inform your clinical assessment.
