Peclet Number Calculator  

Velocity :
v= Pek/ρc_{p}D
Density :
ρ = Pek/vc_{p}D
Heat Capacity :
c_{p} = Pek/vρD
Characteristic Length :
D = Pek/vρc_{p}
Thermal Conductivity :
k =vρc_{p}D/Pe
Where,
Pe = Peclet Number,
v = Velocity,
ρ = Density,
c_{p} = Heat Capacity,
D = Characteristic Length,
k = Thermal Conductivity
Example:
Calculate the Peclet Number for the given details.
Velocity (v) = 5 m/s
Density (ρ) = 5 kg/m^{3}
Heat Capacity (c_{p}) = 10 J/kgK
Characteristic Length (D) = 25 m
Thermal Conductivity (k) = 20 W/mK
Solution:
Apply Formula:
Pe = vρc_{p} D/k
Peclet Number (Pe) = 937.5
