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