Consider the precipitation of a spherical B-rich phase (phase) from a dilute solution ( phase) of B in A. Suppose the original concentration of B in the solid solution is Co-5x10 atoms/cm', the diffusion coefficient of B is D-1010 cm/sec, and the interface transfer parameter of B is M-106 cm/sec. In a quasi-steady state, if the averaged concentration of B in the bulk (C) remains approximately the same as Co. and the concentration of B next to the auß interface is C 4x10 atoms/cm. what are the equilibrium concentration of B in the and the phases (Ca and Cb), when 21 the radius of the particle is r-um: 104 cm and grows at a rate (ar) of 10-7 cm/sec?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
