1. A liquid ( = 600 kg.m/s and = 1300 kg/m3) flows through a bed packed with sand.
The bed has a diameter of 38 mm and a length 16 mm. The mass flow rate of the
liquid through the bed is 5x104 kg/s.
36 BUOYANCY AND STABILITY
Buoyant force: The upward force a fluid exerts on a body immersed in it.
The buoyant force is caused by the increase of pressure with depth in a fluid.
The buoyant force acting on
the plate is equal to the
weight of the liquid
