A1.6 m wide rectangular channel carries 1.8 m3 /s at a depth of 0.85 m. the channel undergoes a smooth transition in which the channel bottom rises 15 cm and contracts to a width of 1.3 m. assuming friction losses are negligible, determine the depth of flow at the transition.

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.
