4. Drag Force Calculation

The ultimate goal of this section is often to calculate the drag force exerted by the fluid on the plate. "Mecanica De Fluidos Cengel 2 Edicion Pdf 595"

$$ F_D = C_f A \frac\rho V^22 $$

$F_D$: Drag Force
$C_f$: Average friction coefficient (calculated above based on $Re_L$)
$A$: Surface area of the plate (wetted area)

6. Example Problem (Typical for this section)

Problem: Air at $20^\circ \textC$ flows over a flat plate of length $L = 2 \text m$ at a velocity of $V = 5 \text m/s$. Determine if the flow is laminar or turbulent at the end of the plate. Alternative Options

Step 1: Look up properties of air at $20^\circ \textC$. $\nu \approx 1.516 \times 10^-5 \text m^2/\texts$.
Step 2: Calculate $Re_L$. $$ Re_L = \fracV L\nu = \frac5 \times 21.516 \times 10^-5 \approx 660,158 $$
Step 3: Compare to critical $Re (5 \times 10^5)$. Since $660,158 > 500,000$, the flow is Turbulent at the trailing edge (and transition occurred earlier on the plate).
Step 4: You would now use the appropriate $C_f$ formula for a mixed or turbulent flow to find the drag.
