1. One of the fundamental equations in fluid flow is the equation of discontinuity. A. True B. False 2. What is the equation for conservation of flow rate of an incompressible fluid through various cross sections of tube? This fluid has a speed of through a cross section and the speed of through a cross section . A. B. 3. Now there is water running through a tube with two cross sections, =2 meter^2 and = 5 meter^2. Known that...
hi do I just use Bernoulli principle to solve? or do I have to solve for -D first could someone help and explain why please. 23) Every few years, winds in the Blue Ridge will attain sustained speeds of 30 m/s when the jet stream descends during early spring. Approximately what is the force due to the Bernoulli effect on a square 10 m x 10 m roof? Assume the air inside the house remains at rest and the pressure...
Problem 3. Consider a pipe containing a steadily flowing inviscid fluid. It has one inlet and branches into two arms so that there are two outlets (see Fig. 1). Flow can be considered uniform and parallel to the walls when entering and exiting the pipe Inlet Pi Outlet ρ2 A2 p, Outlet Figure 1: Flow of fluid through a "T" -junction in a pipe, shown from above (not to scale) Part A (a) The Continuity equation, as given on the...
Fluid Mechanics. Please answer as many as you can. Short answer questions 1) Explain the physical meaning of the acceleration term uVu, where u is the velocity vector in a fluid. 2) Name the two equations that are required to describe the flow of an inertial jet in an incompressible, unstratified fluid. 3) What is the “Continuum Hypothesis”? 4) Describe how a viscous boundary layer adjacent to a solid surface results in transfer of momentum to/from that surface. 5) What...
Can you please explain to me how to do this problem with proper illustrations? Thank you. 2. (10 points) For the molecule, 2-methylbutane, draw the indicated Newman projections through C2-C3 and explain why a difference in potential energy exists between the conformers. ': Draw the lowest energy. Draw a different staggered staggered Newman projection: Newman projection: - Gouche I w Il punt echpsed Explanation:
Tank 1: Tank 2: Water h(t) h(t) Q1 (70 pts). Suppose experiments have been performed to determine the exit velocity (u) as a function of water height (h) for two different tanks. In Tank I, a smooth rounded nozzle with a diameter of a 2 cm is used whereas a square gate opening with a 2 cm side is utilized in Tank 2. The measured flow rates at different tank heights are given further below; the initial height for both...
(i) Calculate the Knudsen number. (ii) Can you use continuum computational fluid dynamics for this and why? (iii) Repeat (i) and (ii) for the case when air is replaced by argon at 5 atm with a molecular diameter of 1.5nm. Homework problem Microfluidics. KT Mean free path, L: where k is Boltzmann's constant k=1.38x10-2)/K V2.P2 Knudsen number: - 1. You are required to model the heat transfer from a new type of hard disk where the gap between a reader...
Think of a time when you have used self-talk—for example, giving yourself “I can do this!” messages when you are striving to meet a challenge, or “what’s the use?” messages when you are discouraged. Did you purposely choose to use self-talk, or did it just happen?
Please provide step by step solution and i will give a positive rating. Many thanks 1)Suppose we have a steady fluid flow through a section of a cylindrical pipe with varying area, with control volume. At the entrance the radius of the pipe r1 = 4m, the flow velocity is U1 = 5 i m/s and at the exit the radius of the pipe is r2 = 2.5 m and the velocity of the flow is U2 = 5 i...
