S>As part of a continuing liquid-metal heat-transfer program at the Brookhaven National Laboratory both local and tube-average heat-transfer coefficients have been obtained for the flow of mercury normal to a staggered tube bank. The bank consisted of sixty 1/2-in tubes, six wide and ten deep arranged an an equilateral-triangular array The paper presents results showang the effects of flow rate. Prandtl number, wetting gas entrainment and tube location on the tube-average coefficients. The angular variation of the local coefficient is not considered here, owing to the fact that the values have not been calculated completely from the original data. The mercury results are compared wath a few results obtained with water in the same equipment. The heat- transfer runs cover the Reynolds number range of 20,000 to 200,000, whereas the water runs cover the range 8000 to 20,000. Pressure-drop results for both water and mercury flow through the tube bank are reported also. The mercury coefficients for tubes in the interior of the tube bank are well represented by the equation Nu = 4.03 + 0.228(Pe)/sup 0.67. (auth)
