Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. Which of the following statements regarding the exhaust volume of local exhaust hoods is incorrect? ( ) (A). The calculation of the exhaust volume for a sealed enclosure should include the amount of air drawn in through the openings. (B) The calculation of the exhaust volume for a fume hood should take into account the amount of polluted gas generated inside the hood. (C) The exhaust volume of a side-intake hood at the workbench is equal to the product of the area of the intake opening and the air suction velocity at that point. (D) When the same exhaust effect is desired, a rectangular intake opening without edges has a higher exhaust volume compared to one with edges.

Which of the following statements regarding the exhaust volume of local exhaust hoods is incorrect? (C) The exhaust volume of a side suction hood should be the product of the suction area and the wind speed at the suction inlet (A). The calculation of the exhaust volume for a sealed hood should include the amount of air drawn in through the openings (B). The calculation of the exhaust volume for a fume hood should take into account the amount of polluted gas generated inside the hood (C); the exhaust volume of a side suction hood on a workbench is equal to the product of the area of the suction inlet and the wind speed at the control point (D). If the same exhaust effect is desired, a rectangular suction inlet without edges around it will have a higher exhaust volume compared to one with edges around it

Which of the following statements regarding the exhaust volume of local exhaust hoods is incorrect? (C) (A). The exhaust volume calculation for a closed hood should include the amount of air drawn in through the openings. (B) The exhaust volume calculation for a fume hood should take into account the amount of polluted gas generated inside the hood. (C) The exhaust volume of a side suction hood at the workbench is equal to the product of the area of the suction opening and the suction velocity at the control point. (D) When the same exhaust effect is desired, a rectangular suction opening without edges around it will have a higher exhaust volume than one with edges surrounding it
