5.15. A small-parts assembly line involves the use of solvents requiring a high level of ventilation. To achieve removal of these toxic gases, a mean velocity of 8 ft/s must be maintained across the cross-section
of a 12 ft high by 30 ft wide room. The toxicants are subsequently removed in a wet scrubber or filter, which causes a pressure drop of 30 lb/ft². Using a Cordier analysis, select the design parameters for a fan that will provide the required flow and pressure rise, while oper ating at or near 90% total efficiency, and that minimizes the diameter of the fan. Give dimensions and speed of the fan and describe the type of fan chosen.
16.36 The air flow to a four-cylinder four-stroke gasoline engine was measured
by means of a 8 cm diameter sharp edged orifice with Ca = 0.65. During

Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (Fig. P12.19). Usually, the drawbridge is lowered to a horizontal position so that the end of the bridge rests on the stone ledge. Unfor- tunately, Lost-a-Lot's squire didn't lower the draw- bridge far enough and stopped it at 0 = 20.0° above the horizontal. The knight and his horse stop when their combined center of mass is d = 1.00 m from the end of the bridge. The uniform bridge is € = 8.00 m long and has mass 2 000 kg. The lift cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h = 12.0 m above the bridge.
