A train that is 1 mile long starts through a tunnel that is also 1 mile long The train is traveling 15 miles per hour How long does it take for the train to get completely out of the tunnel?
The front of the train enters and exits at 15 mph and at 1 mile it takes 1/15 hour. At the xot the back part is just entering, so it takes another 1/15 hour. Total time is 2/15 hour = 2 *x 60/15 = 8 minutes
What is the occupancy load for a 1440 square foot room?
It would depend almost entirely on what that room is USED for, i.e., the type of occupancy. If it is a storage room in a retail store, you are not allowed to have more than one person for each 300 sq ft (i.e., 5 people), but if it is a classroom in a K-12 education occupancy, you would be allowed one for each 20 sq ft of open space (net floorspace), i.e., 72 people. The NFPA Life Safety Code, or other similar code adopted in your jurisdiction, will determine what load factors to use for your particular occupancy, whatever it is. After you know the permissible load by area, you then calculate the permissible exit load, based upon the location, type and width of the various doors. If the exit load is smaller than the area load, your occupancy is limited by the exits.
