A spherical heating element is placed in water at 1 atm. The
sphere has a diameter of 2.88 cm and maintains a constant surface
temperature of 350 K. The water has a bulk temperature of 290 K and
is flowing at 0.72 m/s. What is the rate of heat transfer from the
sphere to the water?
I have no idea how to do this problem, so whatever
coefficients/formulas are needed, I don’t know. That’s what I’m
expecting you all to help me with.
