Water from an industrial process flows through a long pipe of diameter 0.2m at a mass flow of 1.25 kg/s. The surface of the pipe is held at a constant temperature of 10°C. How long must the pipe be if the water enters at 83°C is desired to be cooled to 25°C? Be sure to justify the validity of your chosen correlation.
