Ludwig Prandtl was born on February 4, 1875 and died on August 15, 1953. Ludwig Prandtl would have been 78 years old at the time of death or 140 years old today.
The centrifuge was invented by Antonin Prandtl in 1864. Prandtl designed the device for use on dairy farms to separate the cream from the milk.
The Nusselt number is proportional to the Prandtl number to the nth power, where n is a positive number less than one.
Prandtl number is dimensionless number, denoted by Npr.Npr = Cp (viscosity)/(thermal conductivity) Cp - specific heat, J per ( Kg Kelvin) viscosity in poise (gm per( cm sec)) thermal conductivity in Watt per (meter kelvin) Prandtl number is important in heat transfer.
Prandtl-Glauert singularity, look it up fella.
The ratio between the kinematic viscosity and the thermal diffusivity is called the Prandtl Number.
Antonin Prandtl, however Gustof de Laval invented the first "Modern" centrifuge. http://en.wikipedia.org/wiki/Centrifuge
