The capillary tube — the simplest of refrigerant controls — is the most popular method for metering refrigerant flow from the condenser to the evaporator in compression-type refrigeration systems.
Tube radial distribution chromatography (TRDC) is an innovative separation technique that exploits the spontaneous radial segregation of mixed solvent systems under laminar flow conditions in ...
Gravimetric Capillary is the most common technique used to measure kinematic viscosity. It is temperature controlled, usually 40 ºC for single grade oils, and both 40 and 100 ºC for multi-grade oils.
