The wave resistance and viscous resistance on a model and prototype ship were discussed. For the prototype, \(L=130 \mathrm{~m}\) and \(A=1800 \mathrm{~m}^{2}\). From the data of Figs 7.2 and 7.3, plot on one graph the wave, viscous, and total resistance ( \(\mathrm{N}\) ) experienced by the prototype, as a function of speed. Plot a similar graph for the model. Discuss your results. Finally, plot the power \((\mathrm{kW})\) required for the prototype ship to overcome the total resistance.
