In figure 1, where is the center of gravity of the gate with respect to the liquid surface O 4.0m O 3.67m O 3.33m 3.0m

( computational fluid dynamics question) Question:  If the calculations lag behind the flow of fluid, what factor of the simulation gets affected? Circle Final answer or State it clearly

Problem 1: Pipe Flow This figure shows the cross-section of a circular pipe whose diameter decreases as it changes direction. If the average velocity at the inlet is UoQ/Ao 2 m/s, and the fluid is incompressible, estimate the velocity at Point 2 with the following assumptions: Part A Assume an ideal fluid. U₂ Streamlines Part B Assume a real fluid under laminar flow (estimate with brief explanation). Part C Assume a real fluid under turbulent flow (estimate with brief explanation). Equipotential lines Point 2 Approximate square

Fluid Mechanics Problem: Note: F = ma to find initial (and constant) baseball deceleration. Find flight time of ball. Use projectile motion equations from physics course to find baseball velocity at home plate.

Please do this carefully.

2. The apparatus shown below is designed to measure the density of an unknown fluid (p2₂). The two sides of the device are separated by a movable, frictionless partition. The partition is attached to the immobile sidewalls of the device via springs (different spring constants) on either side. Before pouring fluid into the device, both springs are unstretched. The device has a rectangular cross-section and extends a width w into the page. Derive an expression for the unknown density p2 = f(p1, h₁, h₂, k₁, k2, Ax, g), where Ar is the displacement of the partition relative to its equilibrium location before the fluids are poured into the apparatus. h₁ P1 k₁ 5 P2 ли Ax k₂ h₂
