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.
