Correlations for heat transfer and pressure drop

Nomenclature:

D - Hydraulic diameter
L - Flow length
vel - Fluid velocity
Dens - Density
CP - Specific heat capacity
DV - Dynamic viscosity
KV - Kinematic viscosity = DV/Dens
TC - Thermal conductivity
Beta - Thermal expansion coefficient
T,Surf - Surface temperature
T,Amb - Ambient temperature
dT = T,Surf - T,Amb
Grav - Gravity acceleration
Re - Reynolds number = vel*D/KV
Gr - Grashof number = Grav*Beta*abs(dT)*D^3/KV^2
Pr - Prandtl number = KV*CP/TC
Ra - Rayleigh number = Gr*Pr
Nu - Nusselt number = HTC*D/TC
HTC - Heat transfer coefficient
rlRough - Relative coarseness
rFrict - Friction coefficient for fluid flow pressure drop
Lam - Laminar
Tr - Transient
Turb - Turbulent
