free convection उदाहरण वाक्य

With the help of these lines, parameters such as cloud condensation level, level of free convection, onset of cloud formation . etc . can be derived from the soundings.
When a layer of CIN is present, the layer must be eroded by surface heating or mechanical lifting, so that convective boundary layer parcels may reach their level of free convection ( LFC ).
Moreover, the altitude of their bases can be higher than the level of condensation by convection or even higher than the level of free convection; it depends on the altitude where the forcing occurs.
"' Natural convection "', or "'free convection "', occurs due to temperature differences which affect the density, and thus relative buoyancy, of the fluid.
This second-generation iMac featured a slot-loading optical drive, FireWire, " fanless " operation ( through free convection cooling ), a slightly updated shape, and the option of AirPort wireless networking.

In fluid mechanics, the "'Rayleigh number "'( "'Ra "') for a fluid is a dimensionless number associated with buoyancy-driven flow, also known as free convection or natural convection.
Although forced convection from thermal gas expansion in zero-g does not fuel a fire as well as natural convection in a gravity field, some types of artificial forced convection are far more efficient than free convection, as they are not limited by natural mechanisms.
"' Convective inhibition "'( "'CIN "'or "'CINH "') is a numerical measure in meteorology that indicates the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection.
If this has been done already I would not have to waste a lot of time trying different types of heat transfer fluids and finding in the end they are not as good as water for free convection heat transfer . Preceding contribs ) 02 : 33, 17 June 2014 ( UTC)
After the pannus types, the remaining accessory clouds comprise formations that are associated mainly with upward-growing cumuliform and cumulonimbiform clouds of free convection . " Pileus " is a cap cloud that can form over a cumulonimbus or large cumulus cloud, whereas a " velum " feature is a thin horizontal sheet that sometimes forms like an apron around the middle or in front of the parent cloud.
