The picture doesn't show. There is an arrow going up in the z-direction.You are helping with the design of an air hockey table.  The air hockey puck, a 3/16 in. thick plastic disc of 3 in. diameter, will rest above the surface of the game table on a uniform cushion of air.  If the plastic has a density of 67 lbm/ft3 and the ambient temperature is 60oF, estimate the flow rate of air required to support the puck.  State any assumptions made.  Give your final answer in lbm/in2/s.
