Most deformation occurs along plate boundaries because .

plates are rigid in their interior but the boundaries are in the asthenosphere.
that is where the molten material makes it easy to deform rock the plates are in constant motion and as a result the boundaries are where they interact the plates were broken along their boundaries so that is where they are weakest

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
