Hot and cold stream of water are mixing together as shown in Figure. The temperature of the hot
and cold streams at the inlet are 75 °C and 18 °C, respectively. Mass flow rates of the hot and the
cold streams are (1.50x10^-1) kg and (1.000x10^-1) kg, respectively. Find the temperature of the
mixed stream. The specific heat of the hot water stream is 4000 J/kg-K and the cold stream is 3800
J/kg-K.
Answer should be in °C with three significant figures.
