Capillary tubes are generally used as the metering device on small, fractional-horsepower refrigeration systems. Charging these systems with refrigerant requires a different procedure than those ...

The capillary tube has been used as a refrigerant metering device for many decades. Many HVACR manufacturers are still successfully employing capillary tube metering devices in their latest equipment.

Capillary tube refrigeration systems are integral components in compact refrigeration and air-conditioning units. These systems utilise a narrow, precisely dimensioned tube to regulate the flow of ...

WHEN a capillary-tube viscometer is used for determining the apparent viscosity of a suspension of discrete, solid particles in a liquid, it is found that the measured viscosity varies with the bore ...

Fill a narrow glass capillary tube with water, then turn it horizontal. Conventional wisdom says that the water will remain inside the tube. But a group of scientists in Spain and the UK has found ...

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.
