What is the purpose of a slot on the wing?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Fluids at rest possess no flow energy. a)- true b)- false

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
