Extracted text: 1. Water with an average temperature of 35 °C flows in a pipe of 3 mm diameter and 2 m length. The pipe surface is kept at a constant temperature of 55 °C. If the average velocity of the water is 0.05 m/s, find the convective heat transfer rate under fully developed thermal and hydrodynamic flow condition.
