Turbulent friction coefficient over a plate

Click For Summary
SUMMARY

The discussion focuses on calculating the turbulent friction coefficient (Cf) over a plate using the equation Cf=0.0577(μ/xρUm)0.2. A participant reported discrepancies in their calculated drag coefficient (CDf) of 0.00421 compared to the expected value of 0.00263. The participant referenced a document from Auburn University that clarifies that CD is an integrated average of the local Cf over the surface area, indicating that further integration is necessary after calculating Cf.

PREREQUISITES

Homework Equations


Cf=0.0577(μ/xρUm)0.2

The Attempt at a Solution


I've managed to do parts a) and b), however I don't believe my attempt at the first part is correct as I am using a different Cf than the value used in the mark scheme.

The expression I made for the first part is, 0.0577(μ/ρUm)0.2[x0.8], with limits L and 0.
This gave me a CDf of 0.00421, but it should be 0.00263:oldconfused:.
