Summary: The author considers an arbitrarily shaped body of finite extent that is kept at a constant temperature and immersed in an infinitely large fluid bath. If the temperature on the body is greater than the ambient temperature of the fluid, it is shown that the heat necessary to keep the body temperature fixed is a monotonically increasing function of the flow velocity at infinity. When the temperature on the body is everywhere greater than the ambient temperature, but not constant, the author gives a counter-example that shows that the above theorem does not apply.
