A horizontal, circular free jet of gaseous Carbon Dioxide at 20 C impinges on a rectangular gate holding back seawater at 15.6 C. The center of the jet strikes the gate at the same height as the free surface of the seawater (h= 1.5 m). The jet has a Mach Number of 0.64 and a diameter of 0.25 m. Assume the changes in density of the jet are small and the friction in the hinge is negligible. (a) (b) (d) (e) d Jet Gate Hinge Seawater Problem 4. h Calculate the speed of sound for Carbon Dioxide at 20C. Calculate the velocity of the jet. Draw the necessary Control Volumes and the Free Body Diagrams. Calculate the force of the jet on the plate. Calculate the width of the gate.
