Q16:- A light oil is to be preheated before being fed to a distillation tower. The preheating is to be accomplished in a heat exchanger in which the heating medium is hot oil. The following data are available: Light oil 160,000 1.7 Hot oil 120,000 Mass Ilow rate, kghr Heat capacity, kJ/kg-K Entry temperature, K 1) If the light oil leaves the heat exchanger at 360 K, determine the temperature of the exit hot oil. 2) If the two fluids flow counter-currently through the heat exchanger, determine the maximum attainable temperature of the light oil. 1.8 300 500

Transcribed Image Text:Q16:- A light oil is to be preheated before being fed to a distillation tower. The preheating is
to be accomplished in a heat exchanger in which the heating medium is hot oil. The following
data are available:
Light oil
160,000
Hot oil
Mass flow rate, kg/hr
Heat capacity, kJ/kg-K
| Entry temperature, K
1) If the light oil leaves the heat exchanger at 360 K, determine the temperature of the exit
hot oil. 2) If the two fluids flow counter-currently through the heat exchanger, determine
the maximum attainable temperature of the light oil.
