In a given experiment, a fluid is heated to an average temperature of 200 °C and flows through a plastic tube with an outer diameter of 4 cm and an inner diameter of 3 cm.
a plastic tube with an outer diameter of 4 cm and an inner diameter of 3 cm. The thermal conductivity of the plastic is 0.5 W/m7 K and the convective heat transfer coefficient inside is 300 W/m2 K.
The pipe is located in a space at 30 °C v the heat transfer coefficient on the external surface is 10 W/m2K. (a) What would be the overall heat transfer coefficient? (b) What is the heat loss per unit length of tube?
