A cylindrical tank with a radius of 10 ft and a height of 40 ft is filled with gasoline. given a density of 670 kg/m 3, determine the mass (lbm) of the gasoline in the tank.

Cylinder:

V = r² π h

r = 10 ft = 10 * 0.3048 m = 3.048 m, h = 40 ft = 40 * 0.3084 = 12.336 m.

Density: m / V = 670 kg/m³

V = 3.048 ² · 3.14 · 12.336 = 359.86 m³

m = V · D = 359.86 m² · 670 kg/m³

Answer:

m = 241,106.4 kg.
