In a certain heat exchanger, both the fluids have identical values of the product of the mass flow rate and the specific heat capacity [where, C„ and C„ are the specific heat capacities of the hot-side and cold-side fluids respectively, and ?it is the mass flow-rate of the flowing streams]. The hot fluid enters at 86 °C and leaves at 42 °C and the cold fluid enters at 26 °C and leaves at 55 °C. The effectiveness of the heat exchanger is?
a. 0.16
b. 0.58
c. 0.73
d. 1.0
