1.	If the direction of the wind is at 90° to one of the faces, positive pressure will be produced on __________(a) Windward face(b) Leeward face(c) Two windward faces(d) Two leeward facesThis question was addressed to me during a job interview.Query is from Air Conditioning in section Acoustics and Ventilation of Construction & Building Materials
Answer» Right option is (a) Windward face To elaborate: If the direction of the WIND is at 90° to ONE of the faces, positive PRESSURE will be produced on the windward face. Positive pressure will be produced on TWO windward faces if the direction of the wind is at 45° to one of the faces.
