//Example 6.2
m_dot=10000 //Weak liquor entering in [kg/h]
fr_in=0.04 //Fraciton of caustic soda IN i.e 4%
fr_out=0.25 //Fraciton of caustic soda OUT i.e 25%
//Let mdash_dot be the kg/h of thick liquor leaving
mdash_dot=fr_in*m_dot/fr_out //[kg/h]
//Overall material balance
//kg/h of feed=kg/h of water evaporated +kg/h of thick liquor
//we=water evaporated in kg/h
//Therefore
