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.
