Tw = Tube wall temperature, F |
Flux = Flux rate, Btu/hr-ft2 of bare tube |
do = Outside tube diameter, in |
di = Inside tube diameter, in |
tw = Tube wall thickness, in |
Rfi = Inside fouling factor, hr-ft2-F/Btu |
hi = Fluid film coefficient, Btu/hr-ft2-F |
kw = Thermal conductivity of tube wall, Btu/hr-ft-F |
Tf = Bulk process fluid temperature, F |
