Estimate the heat transfer coefficient for liquid sodium at 1000?F flowing over a 10-row staggered-tube bank of 1 inch diameter tubes arranged in an equilateral-triangular array with a 1.5 pitch-to-diameter ratio. The entering velocity is 2 ft/s, based on the area of the shell, and the tube surface temperature is 400?F. The outlet sodium temperature is 600?F.GIVENLiquid sodium flowing over an equilateral staggered tube bankSodium temperaturesTs,in = 1000?FTs,out = 600?FNumber of tube rows (N) = 10Tube diameter (D) = 1 inch = 0.0833 ftPitch to diameter ratio (S/D) = 1.5Entering velocity (Us) = 2 ft/sTube surface temperature (Tt) = 400?FASSUMPTIONSSteady stateThe correlation of Equation 7.38 can be applied to a pitch-to-diameter ratio of 1.5Tube wall temperature is uniform andconstant
