1.Air flows into the atmosphere from a nozzle and strikes a vertical plate as shown in Fig. P5.28. A horizontal force of 9 N is required to hold the plate in place. Determine the reading on the pressure gage. Assume the flow to be incompressible and frictionless.

2.Give the definition of relative density in terms of void ratio, derive in terms of unit weights.
