7. A product containing 40 % solids at 10 /C enters a direct contact heat exchanger at the rate of 10 kg/s. Saturated steam (of quality 80%) at 350 kPa mixes with the product. The resulting mixture is separated into two streams. The first stream (by-product) leaves at 60 /C and the second stream (product) leaves at 30 /C at the rate of 5 kg/s with a solids content of 60%. Determine the mass flow rate of steam, mass flow rate of the first stream, and the solids content of the first stream. The specific heat of the solids is 3,000 J/kg K.
