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.
Co-efficients of dynamic viscosity and densities for air and water are \(1.86 \times 10^{-5}\) Pa-s, 1.2 kg/m\(^3\) and \(1.01 \times 10^{-3}\) Pa-s, 1000 kg/m\(^3\) respectively.
Drag measured for the model is 2280 N. Drag experienced by the full-scale object is ___ N (rounded off to the nearest integer).
