Consider an oil-to-oil double-pipe heat exchanger whose flow arrangement is not known. The temperature measurements indicate that the cold oil enters at 20°C and leaves at 55°C, while the hot oil enters at 80°C and leaves at 45°C. Do you think this is a parallel-flow or counter-flow heat exchanger? Why? Assuming the mass flow rates of both fluids to be identical, determine the effectiveness of this heat exchanger.

Consider an oil-to-oil double-pipe heat exchanger
whose flow arrangement is not known. The temperature
measurements indicate that the cold oil enters at 20°C and
leaves at 55°C, while the hot oil enters at 80°C and leaves
at 45°C. Do you think this is a parallel-flow or counter-flow
heat exchanger? Why? Assuming the mass flow rates of both
fluids to be identical, determine the effectiveness of this heat
exchanger.
