Hot water at 90 degrees c flows through a carbon-steel tube

Hot water at 90 degrees C flows through a carbon-steel tube whose ID is 2 cm and OD is 3 cm, at a bulk velocity of 30 m/s. The length of the tube is 10 m. The exterior natural convection coefficient is 8 W/m²*K and the ambient temperature is 25 degrees C.

a) Estimate the interior convective heat transfer coefficient.

b) Calculate the rate of heat loss through the wall of the tube.

c) Find the interior surface temperature.
