LMEC-12 Kuyeza Kuchuluka kwa Zamadzimadzi - Njira ya Capillary
Mamasukidwe akayendedwe si ntchito chimagwiritsidwa ntchito zomangamanga ndi kupanga luso, komanso amathandiza pa zamoyo ndi mankhwala. Mwachitsanzo, kuyeza kukula kwa mamasukidwe akayendedwe amwazi ndi chimodzi mwazizindikiro zofunika zaumoyo wamagazi amunthu. Poyerekeza ndi njira yomwe imagwera mpira, kuyesaku kumagwiritsa ntchito lamulo loyenda la viscous fluid mumachubu wama capillary. Ili ndi maubwino ochepera zitsanzo, kutentha kosiyanasiyana komanso kulondola kwamiyeso. Ndizoyenera makamaka zamadzimadzi okhala ndi ma viscosity ang'onoang'ono, monga madzi, mowa, madzi ndi zina zotero Kugwiritsa ntchito chida ichi sikuti kumangowonjezera chidziwitso cha ophunzira, komanso kumawonjezera luso lawo loyesera.
