Hot water at 330 K is transferred through a steel pipe (kpipe = 60 W/m·K) with the outer diameter of 50 mm and the wall thickness of 5 mm. Surrounding environment is air at T¥ = 270 K and V = 10 m/s in cross flow over the pipe. Calculate the heat loss from the pipe to the air per meter of pipe length in W/m.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
