Uniqueness of three different separation operations. Can the following problems be solved uniquely?(a) The feed streams to an adiabatic equilibrium stage consist of liquid and vapor streams of known composition, flow rate,temperature, and pressure. Given the stage (outlet) temperature and pressure, calculate the composition and amounts of equilibrium vapor and liquid leaving.(b) The same as part (a), except that the stage is not adiabatic.(c) A vapor of known T, P, and composition is partially condensed. The outlet P of the condenser and the inlet cooling water T are fixed. Calculate the cooling water required.
