Question:

The hot and cold inlet temperatures to a concentric tube heat exchanger are Th,i = 200C, Tc,i = 100°C, respectively. The outlet temperatures are Th,o = 110°C and Tc,o = 125°C. Is the heat exchanger operating in a parallel flow or in a counterflow configuration? What is the heat exchanger effectiveness? What is the NTU? Phase change does not occur in either fluid.
