Liquid mercury at 0.5 kg/s is to be heated from 300K to 400K by passing it through a 50mm diameter tube whose surface is maintained at 450K. Calculate the required tube length by using an appropriate liquid metal convection heat transfer correlation. Compare your result with that which would have been obtained by using a correlation approximate for Pr > 0.7.
