4.GENERAL METHODS OF CALCULATION OF HEAT EXCHANGERS
4.1. Method of factor F
4.1.2. Example 1
You want to cool 4500 kg / h of an aqueous solution coming from an evaporator from 353 K to 313 K with 18000 kg / h of water at a temperature of 303 K. The heat capacity of dissolution (Cpdiss) is equal to the heat capacity of water (= Cpaigua 1Kcal/Kg ° C). If the global coefficient of heat transmission is 3300 KJ / h · m2 · h, calculate the following sections for a heat exchanger shell and tubes 2-4:
a) Find the value of the heat transferred (q).
b) Find the value of the factor F.
c) Find the area of transmission of heat required (A).
