A helicopter flying with a velocity of 160km/h at elevation 500m above sea level dropped supplies to hit the barracks situated at elevation 200m above sea level. a. Determine the time (in secs) for the supplies to hit the barracks. b. Determine the distance, in meters, from the barracks the supplies should be dropped so that they will fall within the barracks site.

A baghouse (filters) that employs a shaker collection method is being designed to remove 99.75% of incoming stream of sawdust particles originating from a sawmill plant. The manufacturer has specified a woven fabric for cylindrical bags having dimension of 15 cm in diameter and 6 m long. If the filters are treating 450 m3 /min of polluted air, calculate the total fabric area required, and the number of bags required. Assuming that the terminal velocity for sawdust is 1.1 m/min.
