Why do scientists use the concept of ideal fluid flow?, To make fluids move faster, To simplify the analysis of complex fluid motion, To remove all types of fluids, To change fluid properties, Which best describes a nonviscous fluid?, A fluid with high resistance, A fluid with no internal friction, A fluid that cannot flow, A fluid with changing density, What is the main effect of having no viscosity in a fluid?, Objects move without resistance, Fluid becomes compressible, Objects slow down quickly, Fluid changes direction randomly, In steady flow, what remains constant?, Pressure only, Density only, Velocity at each point, Shape of the container, What does the continuity equation mainly describe?, Pressure of fluid, Temperature of fluid, Conservation of fluid flow, Force of fluid, In continuity equation, what remains constant?, Area only, Velocity only, Area and velocity separately, Product of area and velocity, Why is the flow of fluid constant in continuity equation?, Because fluid disappears, Because fluid is compressible, Because fluid is incompressible, Because velocity is zero, What does a streamline represent in fluid dynamics?, The pressure of the fluid, The temperature of the fluid, The path followed by fluid particles, The density of the fluid particles, What does it mean when streamlines are closer together?, The fluid is slower, The fluid pressure is lower, The fluid velocity is higher, The fluid stops moving, Why do streamlines never cross each other?, Because fluid density is always constant, Because fluid cannot flow in two directions., Because pressure is always the same, Because velocity is zero.
