Mass Transfer On moving the feed line (q-line) from saturated liquid feed (vertical position) to saturated vapor feed (horizontal feed), if the slope of both the operating lines are to be increased, then it will result in Increased reflux ratio None of these Increased reboiler load Greater degree of separation with a fixed number of trays Increased reflux ratio None of these Increased reboiler load Greater degree of separation with a fixed number of trays ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The drying time between fixed moisture contents within the 'constant rate period' is proportional to (assuming that drying occurs from all surfaces of the solid) (where, T = thickness of the solid ) T1.5 T3 √T T T1.5 T3 √T T ANSWER DOWNLOAD EXAMIANS APP
