The preperties should then be evaluated at the avenge of the mean irmpeneite. Tw=(Tw+Ta,V2. Talk 8.1. Fer sartalent fors. Equition 8.60 may be wed as a fint uffresination. Liquid mercury flowing at a velocity of 0.0302ms1 is to be heated from Tm,i=300K to Tm,o=400K by passing it through a 50mm inner diameter tube whose (inner) surface is maintained at TS=450K by using steam condensing on the outside of the tube. Calculate the length of the tube in m to an accuracy of at least four decimal places. Hint: the length of the tube can be obtained from the required heat transfer area to heat the mercury from 300K to 400K. Use the log mean temperature difference in Newton's Law of Cooling...
