Resistance of a barge is to be determined from model test data

 

Resistance of a barge is to be determined from model test data. The model is constructed to a scale ratio of 1:13.5, and has length, beam, and draft of 22.0, 4.00, and 0.667 ft, respectively. The test is to simulate performance of the prototype at 8 mph. What must be the model speed in order for the model and prototype to exhibit similar wave drag behavior? Is the boundary layer on the prototype predominantly laminar or turbulent? Does the model boundary layer become turbulent at the comparable point? If not, the model boundary layer could be artificially triggered to turbulent by placing a tripwire across the hull. Where would this be placed? Estimate the skinfriction drag on model and prototype.
