Question
Tomato pulp (40% solids content) is heated by flowing it into a steam injection heater at a rate of 500 kg / hour. 85% quality steam under 180 kPa is supplied to the heater at a rate of 40 kg / hour. If it is assumed that the heat exchanger efficiency is 85% and the initial slurry specific heat is 3.2 kJ / (kg K), the slurry specific heat during the heating process corresponds to the function Cp = Cpw (water fraction) + Cps (solids fraction).
a. Determine the temperature of the product leaving the heater when the initial temperature is 35 ° C. =....° C.
b. Determine the total solids fraction of the product after heating. = ...%
