ABSTRACT
Laminar flow heat transfer coefficients were measured for the flow of ethylene glycol through 3.35 m × 4.8 mm (11 ft × 3/16 in) coiled copper tubing while heating the coil in an agitated water bath at about 65°C (150ºF). The temperature of the exiting ethylene glycol was recorded as a function of flow rate and was used to determine the duty of the copper coil and the experimental heat transfer coefficient. Finally, the experimental results were compared to results from the Seider-Tate correlation. The average error was 15.5% and the maximum experimental error was 24%, which is very reasonable for the laminar flow experiments.
