An infinite span (2D) cylinder (diameter 6cm) serves as a plug between the two airstreams. Upstream V=100m/s Downstream V=10m/s Assuming both air flows to be steady, inviscid and incompressible, and neglecting body forces and weight of the cylinder, determine the magnitude and direction of the net force acting on the cylinder plug. P=1.5x10^5 Pa, T=20 deg C.
