For example, dilution of caustic lye using water (caustic lye 45% NaOH solution). pure solvent phase to a solution phase. SOLVED EXAMPLES Example 6.1: A stream of nitrogen flowing at a rate of 100 kmol/h is heated from 303 K (30 to 373 K (100 °C). Calculate the heat that must be transferred. Data : Cn for nitrogen = 29.5909-5.141 x 10-3T+ 11.1829 x 106 T2-4.968 x 10-9 T³, Solution : Basis : 100 kmol/h of nitrogen gas. Let Q = heat that must be transferred (added to increase the temperature). T2 Q = n T1 T2 Q = nJ (29.5909- 5.141 x 10-3T+ 11.1829 x 10-6 T? -4.968 x 10-9 T) dT 4.968 x 10-9 T1 11.1829 x 10-6 3. 29 5909 (T1-Ti) - 5.141 x 10-3
