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.
The Nusselt number is proportional to the Prandtl number to the nth power, where n is a positive number less than one.

Ludwig Prandtl died on August 15, 1953 at the age of 78.
The ratio between the kinematic viscosity and the thermal diffusivity is called the Prandtl Number.
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 Graetz number is {(Diameter/Length)*Reynolds#*Prandtl#}^(1/3) It is used to characterize the thermal development of pipe flow: if the Graetz number is less than 1000, the thermal profile is fully developed.
The number 4 has no gay significance.
Its significance is that 137 is a prime number
