1-kg/s Glycerin (C₂=2200 J/kg.K) is to be heated from 20°C to 60°C using 2-kg/s Ethylene Glycol (Cp = 2600 J/kg.K) entering the tubes at 90°C in a heat exchanger. The convective heat transfer coefficients for the glycerin and ethylene are hgly = 800- and heth = 1200- respectively. Considering that the tube diameter and length are 2 cm and 2 meters, determine the number of tubes, if the heat exchanger is W m²c m²c² a. Parallel Flow b. 2-shell passes and 4-tube passes
