What Is Murphree Tray Efficiency?

What Is Murphree Tray Efficiency? The Murphree vapor-phase tray efficiency (ηtray) defines the fractional approach to equilibrium for a single cross-flow tray based on the vapor concentrations on the operating and equilibrium lines. … 4 is constant across the tray, and the vapor concentration below the tray is uniform.
