1.	What does the term Positive pressure means?(a) The contaminants of the room should not flow out into the surrounding(b) There should be the balance between the room and surrounding of air and contaminants(c) The pressure makes room isolated from the surrounding and contaminants(d) The air pressure is lower than the surroundingI have been asked this question in an international level competition.The query is from Filtration topic in chapter Unit Operations of Bioprocess Engineering
Answer» Correct answer is (c) The pressure makes room ISOLATED from the surrounding and contaminants To explain: Positive pressure refers to pressure that exceeds the surrounding pressure of any room, chamber or confined SPACE. Positive pressure is maintained in a closed ZONE to ENSURE no outside contaminated gaseous or LIQUID substance can get into that protected zone.
