Question: A ship 100 m long moves at 1.5 m/sec in freshwater at 20C. A 1:100 scale model of the prototype ship is to be tested

A ship 100 m long moves at 1.5 m/sec in freshwater at 20°C. A 1:100 scale model of the prototype ship is to be tested in a towing tank containing a liquid of specific gravity 0.90. What viscosity must this liquid have for both Reynolds and Froude number laws to be satisfied?
