... range of 2.8 × 10 6 − 5.5 × 10 6 based on the plate length and freestream velocity. Results indicate an increase in frictional resistance coefficient C F of up to 7.3% for an unsanded, as-sprayed paint surface compared to a sanded, polished surface. Significant increases in C F were also noted...
