A block in the shape of a rectangular parallelepiped was dipped into gasoline. Its dimensions are 4, 5, 10 cm. Determine the buoyancy force acting on the bar. (Gasoline density 710 kg | m3)
Given:
petrol
V = 4x5x10 cm = 0.04×0.05×0.1 m
p = 710 kg / m3
Find: Fa =?
Decision:
Fa = pgV, p – density, g gravitational acceleration, V volume of a submerged body.
Fa = 710 kg / m3 * 10 N / kg * 0.04 m * 0 * 05m * 0.1 m = 1.42 N
Answer: Fa = 1.42 H
