Capillary Water Pump

The water propagates in the main flow channel and filled junction zone until 6 s.

Capillary water pump. Although it is not shown in the movie this is indicated by the change in the shape of the water front in the inlet. Before you get your hopes up it s definitely no. The capillary pump is one of the simplest passive pumps. Capillary pumping is an attractive means of liquid actuation because it is a passive mechanism i e it does not rely on an external energy supply during operation.

The capillary pumps comprise microstructures of various shapes with dimensions from 15 250 microm which are positioned in the capillary pumps to encode a desired capillary pressure. The given installation is invented in moldova by the author leonid pop. Scientists have figured out how to pump water upwards in a thick tube using a combination of surface tension and water repellent materials. Instead of turning a tree on a table the capillary force pump sketch which i have drawn itself can be used to lift water to a considerable height by using several such capillary tube arrangements on a lengthy vertical shaft with collecting trays in between.

Filling behavior of a liquid inside different types of capillary pumps. The capillary flow rate. From 6 s to 20 s the capillary array exhibits an irregular disorganized suction profile but this can be controlled by a simple rule. The capillary pumps are designed to have a small flow resistance and are preceded by a constricted microchannel which acts as a flow resistance.

This allows water to be lifted in several stages.
