A hot-water stream at 80 °C enters a mixing chamber with a mass flow rate of 0.5 kg/s where is is mixed with a stream of cold water at 20 °C. If it is desired that the mixture leave the chamber at 42 °C, determine the mass flow rate of the cold water stream. Assume all the streams are at the same pressure of 250 kPa. T₁ = 80°C mt=0.5 kg/s T₂ = 20°C A. 0.840 kg/s B. 0.850 kg/s C. 0.865 kg/s D. 0.880 kg/s H₂O T₁ = 42ºC->> (P = 250 kPa)
