The ratio of specific weight of a liquid to the specific weight of pure water at a standard temperature is called

According to Darcy's formula, the loss of head due to friction in the pipe is (where f = Darcy's coefficient, l = Length of pipe, v = Velocity of liquid in pipe, and d = Diameter of pipe)

The body will float if the force of buoyancy is __________ the weight of the liquid displaced.

The specific gravity of an oil whose specific weight is 7.85 kN/m³, is

In a sharp-crested weir, the thickness of the weir is kept less than half of the height of water above the crest of the weir.
