Liquid mercury at 0.5 kg/s is to be heated from 300 to
400 K by passing it through a 50-mm-diameter tube
whose surface is maintained at 450 K. 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 appropriate for Pr>= 0.7.
