Question

Suppose you are designing an air hockey table. The table is| 3.0 × 6.0 ft in area, with is-in-diameter holes spaced every inch in a rectangular grid pattern (2592 holes

total). The required jet speed from each hole is estimated to be 50 ft/s.Your job is to select an appropriate blower that will meet the requirements. Estimate the volumetric flow rate (in ft/min) and pressure rise (in Ib/in³) required of the blower.Hint: Assume that the air is stagnant in the large volume of the manifold under the table surface, and neglect any frictional losses.
