$1)$During a wind tunnel experiment on the flow over an engine nacelle, the following measurements were taken:$-$F$\_$D $=1$N$-$ V $=48\mathrm{.}5$ m$/$s$-\backslash$rho $=1\mathrm{.}2$ kg$/$m $^3-$ T $=$ $$19\backslash$celsius$$-$ Diameter $=50$ mmDetermine the Reynolds number and the drag coefficient $($This was completed in class$)\mathrm{.}2)$ If the model in the wind tunnel was a $1/12$th scale model, determine the equivalent conditions for a full scale model$\mathrm{.}3)$ If a $1/4$th scale model is to be tested in a water tunnel at $80$ F$,$ determine the velocity of the water if the actual car is to be traveling at $100$ ft$/$s in air at the same temperature.Find an equation which relates your experimental drag measurement to the actual car. Make any necessary assumptions to complete the analysis.
