When The Stream Line Streak Line And Path Line Will Be Same? Stream Line Streak Line Particles may change streamline depending on the type of flow May change from instant to instant. Streamlines cannot intersect with each other, they are always parallel. Streak line changes with time. Two streak lines may intersect each other. What
Does The Amount Entering A Control Volume Have To Be Equal To The Amount Of Mass Leaving During An Unsteady Flow Process? No, Amount of mass and energy are different at inlet and out let for unsteady flow process. Does the amount of mass entering a control volume have to be equal to the amount
Does Flow Rate Stay The Same? In most questions, flow remains constant so increasing area will decrease velocity. Is flow rate constant? For flow in a tube, the mass flow rate is a constant. For a constant density flow, if we can determine (or set) the velocity at some known area, the equation tells us
How Do You Know If A Flow Is Uniform? Whereas in real fluids velocity varies across the section. But when the size and shape of cross section are constant along the length of channels under consideration, the flow is said to be uniform. How do you determine if a flow is uniform? In uniform flow
What Is Gradually Varied Flow? A gradually varied flow (GVF) profile is a plot of water depth versus distance along the channel as the water depth gradually achieves normal depth. … A GVF profile is also known as a water depth profile, backwater calculation, and non-uniform flow computation. It is for steady state flows (discharge
Under What Conditions Will Pathlines Streamlines And Streaklines Be Considered The Same? Streamlines, streaklines and pathlines are field lines in a fluid flow. They differ only when the flow changes with time, that is, when the flow is not steady. Under what condition do streamlines of a flow coincide with the streak lines? It is
What Does It Mean When A Flow Is Fully Developed? Fully developed flow implies that the velocity profile does not change in the fluid flow direction hence the momentum also does not change in the flow direction. In such a case, the pressure in the flow direction will balance the shear stress near the wall.
What Is A Fully Developed Flow? Fully developed flow implies that the velocity profile does not change in the fluid flow direction hence the momentum also does not change in the flow direction. In such a case, the pressure in the flow direction will balance the shear stress near the wall. What is a fully
What Is Continuity Equation For Fluid Flow? In fluid dynamics, the continuity equation states that the rate at which mass enters a system is equal to the rate at which mass leaves the system plus the accumulation of mass within the system. ∂ρ ∂t + ∇. (ρ q)=0. What is meant by continuity equation? The
What Is A Developing Flow? When the boundary layer expands to fill the entire pipe, the developing flow becomes a fully developed flow, where flow characteristics no longer change with increased distance along the pipe. … Many different entrance lengths exist to describe a variety of flow conditions. What causes fully developed flow? Fully developed
