Ayacht of charactersitic length 35.82 m is being designed. the density and absolute viscosity of the water from the ocean where it would be used is 1022.8 kg/m^3 and 0.00106 pa. s respectively. the froude number associated with this concept yacht at its cruising speed is 0.71. if the 0.185 scaled down version of a yacht has to be tested in a towing tank which has a fluid of density of 980 kg/m"". what should be the absolute viscosity (rounded of to 6 decimal places) of the fluid in the towing tank to obtain a dimensionally similar flow condition. also calculate the cruising speed for the original yacht and give the answer in knots. viscosity of the fluid in the towing tank = cruising speed of the yacht =
