The Prandtl Number is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity - and can be expressed as: Pr = %3D CpK where u = absolute viscosity, cp = specific heat, and k = thermal conductivity. Calculate %3D the Prandtl number for a fluid with an absolute viscosity of 15 cP, specific heat of 1163 J/kg-°F, and thermal conductivity of o.o06 BTU/h-ft-°F.

Steady State Model

The steady-state model typically states that the entire universe is always enlarging, although it balances a fixed average density and matter that is being constantly generated to make new galaxies, star forms at a similar rate that the previous ones get indistinguishable due to the growing range and velocity of recession.
