Question: Air at 15 C flows into the atmosphere from a nozzle and strikes a vertical plate as shown in the figure below. A horizontal force F = 12 N is required to hold the plate in place. Assume the flow to be incompressible and frictionless. Determine the reading on the pressure gage? Given that density of air at 15oC is 1.225 kg/m3

Given Answer: 1.82 kPa
