give an example of a dynamic fluid force. describe the situation/movement where the dynamic fluid force is present, classify it as a drag or lift force, point out if the goal of the movement is to maximize or minimize the drag force and how that is accomplished practically. Finally point out the specific component of the equation that is altered during this situation

What is importance of complex Analysis in Fluid Dynamics? Find the Magnitude at any velocity in a two dimensional motion?

A cylinder is formed by bolting two semicylindrical channelstogether on the inside, as shown in Fig.  Thereare 10 bolts per meter of width on each side, and the insidepressure is 50 kPa (gage). Using potential theory for theoutside pressure, compute the tension force in each bolt ifthe fluid outside is sea-level air.

I got an answer of x = 89.4mm And a reynolds number of  1.09 * 10^5   Just want to confirm my math

What is the importance of expressing equations describing fluid dynamics in terms of non-dimensional parameters?Give two examples a of non-dimensional parameters used in fluid mechanics explaining their significance.

2. Consider the boundary-layer momentum equation for steady incompressible flow in two dimen- sions: ди dpe ду du du + po ay dx Assume the viscosity, u, to be constant. What does this equation simplifies to at a stationary solid surface? Based on this result, is a boundary layer more likely to separate in a favourable gradient (pressure decreasing) or an adverse pressure gradient? Sketch the velocity profile of a boundary layer that is attached and one that is separated. pressure

The actual car will be running at V= 35 km/h at p-1 atm and T=0°C (the air density and viscosity are 1.292 kg/m3, and 1.338 x 105 m2/s, respectively). A one-fifth scale car model is being tested at the wind tunnel at 198.3 km/h at 1 atm and 20°C. (The air density and viscosity are 1.204 kg/m³, and 1.516 x 10$ m²/s, respectively). The average drag force on the model is 50 N. What is the drag force on the prototype? Note that dimensionless drag is Cp 1/2pV² A O 41.8 N O 50 N O 15.0 N O 44.2 N O 8.4 N O 38.9 N

What role does computational fluid dynamics (CFD) play in optimizing the design and performance of aerodynamic systems, such as aircraft and wind turbines, and how has the advancement of CFD software and hardware influenced engineering practices in these domains?

I want the detailed solution to understand a question

While you looking for a gift, you noticed a table tennis ball suspended in midair in a jet of air blown from the outlet of a house of tank type vacuum cleaner.  The ball bounces around a bit but always moves back toward the center of the jet, EVEN if the jet is tilted a bit from the vertical. Why does the ball always get pulled back to the center? Explain the behavior using your understanding of fluid dynamics.
