Three streams of products (all at 80 °C) mix together in a mixer. The first stream enters at the rate of 10 kg/s and has a specific heat of 4,000 J/kg K. The second stream is pure water, and it enters at the rate of 3 kg/s. The third stream has a specific heat of 3,600 J/kg K. The resulting mixture (product A) enters an indirect contact cooler that uses water at 5 kg/s. The cooling water enters at 5°C and leaves at 25°C. Another product at 40°C (specific heat = 3,000 J/kg K) flowing at the rate of 4 kg/s also enters this cooler and mixes with product A. If the final product (product B) leaves the cooler at the rate of 21 kg/s, determine its temperature. Take into account the fact that the specific heat of water varies with temperature. cp(1)= specific heat of water at 80 °C = 4194 J/kg K cp(3) = specific heat of water at 5 °C = 4206 J/kg K cp(4) = specific heat of water at 25 °C = 4178 J/kg

Three streams of products (all at 80 °C) mix together in a mixer. The first stream enters at the rate of 10 kg/s and has a specific heat of 4,000 J/kg K. The second stream is pure water, and it enters at the rate of 3 kg/s. The third stream has a specific heat of 3,600 J/kg K. The resulting mixture (product A) enters an indirect contact cooler that uses water at 5 kg/s. The cooling water enters at 5°C and leaves at 25°C. Another product at 40°C (specific heat = 3,000 J/kg K) flowing at the rate of 4 kg/s also enters this cooler and mixes with product A.
