Determine the heat transfer coefficient for liquid bismuth flowing through an annulus (5 cm ID, 6.1 cm OD) at a velocity of 4.5 m/s. The wall temperature of the inner surface is 427°C and the bismuth is at 316°C. It may be assumed that heat losses from the outer surface are negligible.
GIVEN
Liquid bismuth flowing through an annulus
Annulus diameters
Di = 5 cm = 0.05 m
Do = 6.1 cm = 0.061 m
Bismuth velocity (V) = 4.5 m/s
Temperature
Inner wall surface (Tsi) = 427°C
Bismuth (Tb) = 316°C
ASSUMPTIONS
Steady state
Heat losses from outer surfaces are negligible
