The four major factors that impact the pressure drop of the collector are as following:
The quantity of the liquid flowing through the collector：When the diameter and the coarseness of the
draining pipe and collecting pipe for the collector is fixed, the pressure drop increases along with the
quantity increase of the liquid flowing through the collector.
The diameter of the draining pipe and collecting pipe for the collector： When the coarseness of the inner
wall of the pipe and the liquid quantity is fixed, the pressure drop increases along with the decrease of
the diameter.
The coarseness of the inner wall of the draining pipe and collecting pipe for the collector: When the
liquid quantity and pipe diameter is fixed, the pressure drop increases along with the increase of the
coarseness of the pipe's inner wall.
The liquid viscosity: when other conditions are the same, the pressure drop increases along with the
viscosity increase of the liquid flowing in through the collector.
