Question

A 5.5-kg plastic tank that has a volume of 9.7 m^3m 3 is filled with an unknown gas. Assuming the weight of the filled tank is 265 N, determine the specific volume of the gas in SI units

Answer 1

First, we will find the mass of filled tank :

M = W / g

M = 265 / 9.81

M = 27 kg

Next, we will find the mass of the gas :

m = 27 - 5.5

m = 21.5 kg

Finally, we will find it's specific volume :

v = V / m

v = 9.7 / 21.5

v = 0.451 m³/kg
