Steam with 80% quality is being used to heat a 40% total
solids tomato purée as it flows through a steam injection heater
at a rate of 400 kg/h. The steam is generated at 169.06 kPa
and is fl owing to the heater at a rate of 50 kg/h. Assume that
the heat exchanger effi ciency is 85%. If the specifi c heat of
the product is 3.2 kJ/(kg K), determine the temperature of the
product leaving the heater when the initial temperature is
50C. Determine the total solids content of the product after
heating. Assume the specifi c heat of the purée is not infl uenced by the heating proce
