A cylindrical object of diameter 900 mm is designed to move axially in air at 60 m/s. Its drag is estimated on a geometrically half-scaled model in water, assuming flow similarity.
Coefficients of dynamic viscosity and densities for air and water are 1.86 x 10-5 Pa-s, 1.2 kg/m3 and 1.01 x 10-3 Pa-s, 1000 kg/m3 respectively.
Drag measured for the model is 2280 N. Drag experienced by the full-scale object is _______ N. (rounded off to the nearest integer)
