An object falls in air down a long vertical chute. The speed of the object is constant at \(3 \mathrm{~m} / \mathrm{s}\). The flow pattern around the object is shown. The static pressure is uniform across sections (1) and (2); pressure is atmospheric at section (1). The effective flow area at section (2) is 20 percent of the chute area. Frictional effects between sections (1) and (2) are negligible. Evaluate the flow speed relative to the object at section (2). Calculate the static pressure at section (2). Determine the mass of the object.
