Transcribed Image Text:A long, horizontal, cylindrical steel reactor, 1 m in diameter, has a surface temperature of 300°C. The
emissivity of the steel is 0.6, and the heat transfer coefficient for natural convection is 5 W m² K ¹.
Heat is lost by convection to the air at 15°C, and also by radiation to the surroundings, which can be
considered to be a black body at 15°C.
a) Calculate the total heat loss per metre length of the reactor, and the proportions lost by convection
and radiation.
