1 Total costs (materials and labor) for professional installation of a bathroom tile floor averages $10-$40 a square foot, but it can cost more for custom tiles, detailed patterns or unusual room layouts.
Rayleigh number, Ra, is a dimensionless term used in the calculation of natural convection. where g is acceleration due to gravity, Î²' is coefficient of thermal expansion of the fluid, Î´T is temperature difference, x is length, Î½ is kinematic viscosity and Îº is thermal diffusivity of the fluid. Gr is the Grashof Number and Pr is the Prandtl Number.
On the Internet, some sites outside the U.S. use the compound designation milliard/billion to designate the number 1 000 000 000. In science, the names of large numbers are usually avoided completely by using the appropriate SI prefixes. Thus 10 9 watts is a gigawatt and 10 12 joules is a terajoule.
