- The film temperature is often used as the temperature at which fluid properties are calculated when using Prandtl number, Nusselt number, Reynolds number or Grashof number to calculate a heat transfer coefficient, because it is a reasonable first approximation to the temperature within the convection boundary layer.
- Where q / A is the total heat flux, D _ b is the maximum bubble diameter as it leaves the surface,-is the excess temperature, k _ L is the thermal conductivity of the liquid and Pr _ L is the Prandtl number of the liquid.
- Where " S T ", " T T " denote the salinity and temperature at top layer, " S B ", " T B " denote the salinity and temperature at bottom layer, Ra is the Rayleigh Number, and Pr is the Prandtl Number.
- Given Reynolds number is a constant for a hydrodynamically fully developed flow ( where the velocity of the flow remains unchanged ), the equation above indicates that the thermal entrance length is proportional to the Prandtl number [ 1 ], which is defined as the ratio of momentum diffusion rate to the thermal diffusion rate of a fluid.
- Under standard nondimensionalisation of the equations, a number of parameters arise that govern the problem : Ck is the thermal dissipation parameter ( related to the thermal conductivity, K ), Pr = �cp / K is the Prandtl number, ? = ?cp?0 / K, and the Chandrasekhar number Q = B2 0 d2 / ( ?�� ), with ? the magnetic permeability, measures the strength B0 of this background magnetic field ( although a related parameter appears explicitly in the equations, ? = Pr?QC2k ).
- For a fluid flowing in a straight circular pipe with a Reynolds number between 10, 000 and 120, 000 ( in the turbulent pipe flow range ), when the fluid's Prandtl number is between 0.7 and 120, for a location far from the pipe entrance ( more than 10 pipe diameters; more than 50 diameters according to many authors ) or other flow disturbances, and when the pipe surface is hydraulically smooth, the heat transfer coefficient between the bulk of the fluid and the pipe surface can be expressed explicitly as:
- For a correlation for a given geometry ( e . g . spheres, plates, cylinders, etc . ), a heat transfer correlation ( often more readily available from literature and experimental work, and easier to determine ) for the Nusselt number ( Nu ) in terms of the Reynolds number ( Re ) and the Prandtl number ( Pr ) can be used as a mass transfer correlation by replacing the Prandtl number with the analogous dimensionless number for mass transfer, the Schmidt number, and replacing the Nusselt number with the analogous dimensionless number for mass transfer, the Sherwood number.
- For a correlation for a given geometry ( e . g . spheres, plates, cylinders, etc . ), a heat transfer correlation ( often more readily available from literature and experimental work, and easier to determine ) for the Nusselt number ( Nu ) in terms of the Reynolds number ( Re ) and the Prandtl number ( Pr ) can be used as a mass transfer correlation by replacing the Prandtl number with the analogous dimensionless number for mass transfer, the Schmidt number, and replacing the Nusselt number with the analogous dimensionless number for mass transfer, the Sherwood number.
- For heat transfer, where " Nu " is the Nusselt number, " Re " is the standard Reynolds number based on the inner diameter of the tube, " Re "'is the specific Reynolds number based on the wiping frequency, " Pr " is the Prandtl number, " Fa " is the Fanning friction factor, " L " is the length of the tube, " D " is the inner diameter of the tube, " n " is the number of blades and the dots account for any other relevant dimensionless parameters.
