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 specific heat of the purée is not infl uenced by the heating process.
