A circular glass plate has a diameter of 350 mm (13.78 in) and athickness of 10 mm (0.394 in). The edge of the plate is clamped,and air at 258C (778F) is on both sides of the plate. Determine thetransmission loss for the plate for a frequency of [A] 250 Hz and [B]1000 Hz.

The steel water pipe has an inner diameter of 12 in and wall thickness 0.25 in. If the valve a is closed and the water pressure is 300 psi, determine the longitudinal and hoop stress developed in the wall of the pipe. 

A bullet enters a 50 mm plank with a speed of 600 m/s and leaves with a speed of 24 m/s. Determine the thickness of the plank that can be penetrated by the bullet.

Air at 86F and 80% relative humidity is delivered to a cooling unit by means of a 6-inch internal diameter circular duct. The velocity of this air in the duct is 1000 feet per minute. In the unit, the air is cooled to 59.9F, condensing some of the water in the air. Determine the flow rate of the condensed water and the amount of energy that must be removed from the unit.
