A continuous mixing operation is carried out by adding 0.3 kg/hr of calcium chloride crystals to a pure water stream flowing at 1 kg/hour.
a. If both streams are at 25◦C when they enter the mixer, what is the temperature of the exit stream?
b. How much heat would have to be removed if the operation were to be carried out isothermally at 25◦C?
The heat capacity of CaCl crystals is approximated by c_p = 0.636 + 1.41 × 10^–4T J/g K, where T is in K.
