Question

Please answer the following questions to the best of your ability. The layer near any fixed surface in a moving stream in which showing strokes and viscous forces are important is the: Boundary layer Friction layer Transition layer Turbulence layer If a fluid flow field has a vorticity value equal to zero, then that flow K classified as rotational True False A specific collection of matter of fixed identity (always the same atoms or fluid particles), which may move, flow, and interact with its surroundings is defined as a control volume. True False The Eulerian method of flow description involve, "tagging' individuals fluid particles as they move about space. Using the method of superposition, a half body can be approximated using the combination of: The Bernoulli equation can be used between any two points in a steady, inviscid flow field for: compressible flows irrotational flows potential flows uniform flows The normal vector is related to the control surface as follows: Normal vector always acts in the negative direction Normal vector always acts parallel to the control surface Normal vector always acts perpendicular to the control surface Normal vector always acts in the positive direction The relative velocity is defined as the: Fluid velocity as seen from a fixed coordinate system Fluid velocity as seen an observer moving with the control volume Fluid velocity as seen by a stationary observer in a fixed coordinate system Not enough information given
