Asmooth steel (sg = 7.86) sphere is dropped in gasoline at 20°c. ignoring its acceleration phase, what will be its terminal (constant) fall velocity? take d = 0.5 cm. for gasoline at 20°c, take rho ≈ 680 kg/m3 and μ ≈ 2.92e−4 kg/m⋅s. for steel, take rho ≈ 7800 kg/m3. take π = 22/7. round the answer to one decimal digit. take cd ≈ 0.4.
