points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...
Density is the mass per unit volume of a material. i.e. density is the mass of 1 cm 3 or 1 m 3 of a material. The density of aluminium is 2.7 g/cm 3 – this means that 1 cm 3 of aluminium has a ...
Density is usually calculated using a mathematical function of temperature, salinity, and pressure, sometimes called an equation of state. For many years the internationally accepted standard for ...
