Industrial Skills Area: Descriptions, Calculations & Industrial Applications
Description: AreaA Two-Dimensional Quantity • Area measurements utilize linear measurements to calculate the number of unit squares within a given boundary. • Measurements of area are expressed in “square units” such as square inches, square feet, square meters, etc. • They have length and width but thickness is not considered in the calculations. • Never mix units in the same calculation.
Industrial Applications:Common Quantities and Conversions • 1 square foot = 144 square inches • 1 square yard = 9 square feet = 1,296 sq. in. • 1 cubic foot = 1,728 cubic inches • 1 cubic yard = 27 cubic feet = 46,656 cu. in. • 1 cubic foot = 7.47 gallons of water* • 1 gallon of water = 8.3453 pounds* • 1 square centimeter = 100 square millimeters • 1 square meter =10,000 sq.cm.=1,000,000 sq.mm • 1 cubic meter = 1,000,000,000 cubic millimeters • 1 cubic meter = 1,000 liters of water* • 1 cubic meter = 264.2 gallons of water* • 1 liter of water = 1.000 Kilogram*
Industrial Applications:Exhaust Fan Calculations • NC Mechanical Code Requirements for Exhaust Fans: • Autopsy Room: .50 cubic foot per min. per sq. ft. • Pet Store: 1 cubic foot per minute per square foot • Smoking Lounge: 60 cu.ft. per min per person • Exhaust Fan Specifications: • Economy Model: 60 Cubic Feet per Minute (CFM) • Commercial Model: 50 CFM • Commercial Model: 80 CFM
Industrial Applications:Exhaust Fan Questions • If the room in question were to be used as a pet storage facility, which exhaust fan would be needed? • If the room in question were to be used as to perform autopsies, which exhaust fan would be needed? • If the room in question were to be used by a person who will be smoking in their office, which exhaust fan would be needed?
Industrial Applications:Room Calculations Inside Dimensions: 96” wide x 102” long 96” x 102” = 9,792 sq.in. divided by 144 sq.in. = 68 sq. feet (8ft. x 8.5ft. = 68 square feet) Inside Dimensions: 96” wide x 102” long x 99.5” high 96” x 102” x 99.5” = 974,304 cu.in. divided by 1,728 cu.in. = 563.8 cubic feet (8ft. x 8.5ft. x 8.3ft. = 564.4 cubic feet)
Industrial Applications:Exhaust Fan Questions • If the room in question were to be used as a pet storage facility, which exhaust fan would be needed? (80 CFM) • If the room in question were to be used as to perform autopsies, which exhaust fan would be needed? (50 CFM) • If the room in question were to be used by a person who will be smoking in their office, which exhaust fan would be needed? (60 CFM)
