A saline water is fed to a reverse osmosis unit at flow rate of 10.5 LPM. Rotameter connected to reject line reads reads 8 LPM.conductivity meter installed in reject and permeate line reads 15.2 milli Siemens /cm and 300 micro Siemens /cm respectively. Find % recovery and % salt rejection of RO unit . Calibration equation of conductivity probe C=0.314 * conductivity. Where C is in g/L and conductivity is mSiemens /cm
