Ammonia is absorbed from air stream using water at 0 °c and 1.30 atm. the entering water stream is pure water. the entering vapor is 18 mol% ammonia. the goal is to recover 82% of the ammonia in the water outlet stream. the inlet gas flow rate is 50 kmol/hr. absorbent flow rate is 1.5 times the minimum solvent rate. equilibrium data are given below. assume dalton’s law applies. 1st column ‘g nh3/1g h2o’: 0.05 | 0.075 | 0.100 | 0.15 | 0.20 | 0.25 | 0.30 | 0.40 | 0.50 | 0.60 |‘partial pressure of nh3, mmhg’: 11.2 | 17.7 | 25.1 | 42.7 | 64 | 89.5 | 119 | 190 | 275 | 380

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
