Suppose that 2 people exercising in an enclosed room are each generating about 2.400 BTUs of body heat per

noname [10]

Answer:

0.002 BTUs per cubic foot heat is produced per hour

Step-by-step explanation:

Given:

Number of person = 2

Amount of heat produced by one person = 2.400 BTU

Dimension of the room = 20 ft x 12 ft x 10 ft

To Find:

How many BTUs per cubic foot do they produce in 1 hour = ?

Solution:

E = $\frac{ \text{(2400 Btu/ person hr}) (\text{Number of Hours}) (\text{Number of persons }) }{\text {volume of the room}}$

Substituting the values

E = $\frac{ \text{(2400 Btu/ person hr}) (1) ( 2) }{20 ft \times 12 ft \times 10 ft}$

E = $\frac{4.800}{2400}$

E = 0.002 BTU per cubic feet
