2.23. A stream of warm water is produced in a steady-flow mixing process by combining 1.0 kg s- of cool water at 25°C with 0.8 kg s- of hot water at 75°C. During mixing. heat is lost to the surroundings at the rate of 30 kl s. What is the temperature of the warm-water stream? Assume the specific heat of water constant at 4.18 kJ kg- K-1.
