1.	If the direction of the wind is at 45° to one of the faces, negative pressure will be produced on __________(a) Windward face(b) Leeward face(c) Two windward faces(d) Two leeward facesI had been asked this question in class test.Enquiry is from Air Conditioning topic in chapter Acoustics and Ventilation of Construction & Building Materials
Answer» Correct OPTION is (d) TWO leeward faces Explanation: If the direction of the wind is at 45° to ONE of the faces, NEGATIVE pressure will be produced on two leeward faces. Negative pressure will be produced on one leeward face if the direction of the wind is at 90° to one of the faces.
