A model of submarine is scaled down to 1/25 of the prototype and is to be tested in a wind tunnel. The speed of the prototype at which we are to estimate the drag is 10 m/s. The ratio of the drag between the model and the prototype is = 1.21 x 10-2 cm²/s, Vair = 1.64 x 10-1 cm²/s and Psea water = 1027 kg/m³. Pair = 1.34 [Take Vsea water kg/m³]

A model of submarine is scaled down to 1/25 of the prototype and is to be tested in a wind tunnel.
The speed of the prototype at which we are to estimate the drag is 10 m/s. The ratio of the drag
between the model and the prototype is
1.21 x 10-2 cm²/s, Vair = 1.64 x 10-1 cm²/s and Psea water =
[Take Vsea water
kg/m³]
1027 kg/m³, Pair = 1.34
