Problem 1 Air Flows Steadily Through A Circular Jet Ejector The Primary Jet Flows Through A 20 Cm Diameter Tube With 1 (58.83 KiB) Viewed 58 times

Problem 1. - Air flows steadily through a circular jet ejector. The primary jet flows through a 20 cm diameter tube with a velocity of 30 m/s. The secondary flow is through the annular region that surrounds the primary jet. The outer diameter of the annular duct is 40 cm and the velocity entering the annulus is 15 m/s. If the flows at both the inlet and exit are uniform, determine the exit velocity. Assume the air speeds are small enough so that the flow may be treated as an incompressible flow, i.e., one in which the density is constant. Problem 2. - A gas flows steadily in a 2.0 cm diameter circular tube with a uniform velocity of 1.0 cm/s and a density po. At a cross section farther down the tube, the velocity distribution is given by V - 20.[1-(1/R)-), with r in centimeters. Find U., assuming the gas density to be po[1+(r/R):]
