Select the correct answer. The gas in a sealed container has an absolute pressure of 9.25 atmospheres. If the air around the con
tainer is at standard pressure, what is the gauge pressure inside the container? A. 0.759 atm B. 8.25 atm C. 10.25 atm D. 113 atm
2 answers:
Answer: B) 8.25 atm.
Explanation: Absolute pressure is the sum of gauge pressure and atmospheric pressure.
Atmosphere pressure is given as 9.25 atm and the atmospheric pressure is 1.00 atm.
Let's plug in the values in the above formula:
9.25 atm = + 1.00 atm
= 9.25 atm - 1.00 atm
= 8.25 atm
So, gauge pressure inside the container is 8,25 atm and hence the right option is B.

The answer to the question is;
The occupant load of the store having a floor area of 100,000 ft² is 3,317.86 persons.
Explanation:
Based on NFPA guidelines we have for sales on street floor, the allowable occupant load factor per person is 30 ft²
That is where the floor area is 100,000 square feet we have the number of allowable occupant given by
(100,000 ft²)/(30 ft²/Person) = or 3,333 persons
That is the occupant load of the store if the floor area is 100,000 square feet = 3,333 persons
Based on m² we have 9,290 m² will require 2.8 m²/person
which gives;
(9,290 m²)/(2.8 m²/person) = = 23225/7 or 3,317.86 persons
Therefore applying safety, we go with the lesser number and we have
The occupant load of the store having a floor area of 9,290 m² = 3,317.86 persons.
