A blimp is approximated by a prolate spheroid 90 m long and 30 m in diameter. estimate the weight of gas within the blimp for (a) helium at 1.1 atm and (b) air at 1.0 atm.'

Respuesta :

(a) Let's start by calculating the helium's weight. We'll apply the well-known weight equation:

W helium =m helium ⋅g

where m helium is the mass of the helium and g is the gravity.

=>W helium =ρ helium ⋅V⋅g

putting the values we get

ρ helium =0.183 kg/ m^3

Therefore, W helilum =76.2 kN

(b) The weight of the air will also be determined in the same manner:

W air =ρ air ⋅V⋅g

=> ρ air =1.205 kg/ m^3

Therefore after substituting the values we get,

W air = 501.35 kN
