Natural convection is a type of flow, of motion of a liquid such as water or a gas such as air, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but by some parts of the fluid being heavier than other parts. In most cases this leads to natural circulation, the ability of a fluid in a system to circulate continuously, with gravity and ...

The viscosity of a typical endothermic hydrocarbon fuel (RP-3) at critical and supercritical conditions is measured using a novel viscosity measurement method by expanding the classical capillary method, and it can be applied to the viscosity measurement of single phase flow, including supercritical fluids. The measurement covers the temperature range of (298 to 788) K under pressures from (2 ...

There are good technical reasons for the stated range of 20 to 60 seconds. A material approaching zero viscosity will have an efflux time from the #2 cup of 16.3 seconds. Viscosity of a material has very little influence on cup drain time when near this minimum. Please note the following centistoke - drain time seconds relationship:
