Answer:
a) Specific volume of the air in balloon is
b)The weight of the air within the balloon is 1,126.09 lbf.
Explanation:
Mass of air, m = 35 lbm
Volume of the air = V
Diameter of balloon = d = 10 ft
radius of the balloon = r= 0.5 d = 5 ft
Volume of balloon = V
Specific volume of the air in balloon = S
Specific volume of the air in balloon is
Weight of the air = W
Acceleration due to gravity =
Weight = m\times g[/tex]
The weight of the air within the balloon is 1,126.09 lbf.
