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 =
Substituting the values
E = 
E = 
E = 0.002 BTU per cubic feet
Answer:
312π mm³
Step-by-step explanation:
Given:
Oblique cone height, h = 14 mm
radius of half sphere = base radius of cone, r = 6 mm
Recall the volume of 1/2 - sphere
= 1/2 x volume of sphere
= 1/2 x (4π/3) r³
= 1/2 x (4π/3) (6)³
= 144π
Also volume of an oblique cone =
=volume of a right cone
= (π/3) r²h
= (π/3) 6²(14)
=168π
Volume of composite figure = 144π + 168π = 312π mm³
