4-13. A flash unit is used to separate vapor and liquid streams from a liquid stream by lowering its pressure before it enters the flash unit. The feed stream is pure liquid water and its mass flow rate is 1000 kg/hr. Twenty percent (by mass) of the feed stream leaves the flash unit with a density p 10 kg/m. The remainder of the feed stream leaves the flash unit as liquid water with a density p 1000 kg/m Determine the following: 3 1. The mass flow rates of the exit streams in kg/s. 2. volumetric flow rates of exit streams in m /s. Section 4.6 4-14. Show that Eq. 4-70 results from Eq. 4-69 when either c v n or x is constant over the area of the exit.
