An apartment complex has a floor plan with the dimensions shown. To effectively air condition a room, 20BTU's (British Thermal U
marysya [2.9K]

The dimensions of the room is not given. Lets assume a value and calculate BTU accordingly.

Answer and Explanation:

BTU, or British Thermal Unit, is defined as the amount of heat required to raise the temperature of 1 pound of water by 1° F.

In other words,BTU's measures the amount of heat an AC (or any other cooling unit) can remove from a room per hour. Higher the BTU, the more powerful the cooling.

Calculation:

Lets assume that a room is 10 feet wide and 14 feet long.

  • Step 1

Calculate the size of the room by multiplying the height of the room with its width:

size of the room= 10 × 14

                          = 140 square feet

  • Step 2

Then multiply the size of the room that you obtained in step 1 with 20 BTU per square foot, in order to get the minimum BTU's required for AC to cool a room,

140 × 20= 2800

 2800 BTU cooling capacity is required.
