However, this system offers a low pressure drop across the mill thus requiring a circulating fan with lower power.

Pressure drop - Wikipedia

Pressure drop is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through the tube. The main determinants of resistance to fluid flow are fluid velocity through the pipe and fluid viscosity.Pressure drop increases proportionally to the ...

Pressure drop. The flow resistance of a liquid in a component results in a loss of pressure. If the pressure is measured with a pressure gauge (Figure 7.10) before and after the component, the pressure will be lower on the discharge side. The component, for instance a shut-off valve, causes a pressure drop in the line.
