Why should you use CFD when we know empirical and semi-empirical models have worked before? correct answer: Because it is with CFD possible to model new equipment which has not yet been tested. Thus one can simulate performance of the equipment before spending tons of money to test in reality. What can you simulate with CFD? correct answer: CFD gives a detailed analysis of flows, heat transfer and mass transfer. Can study transport of chemical species, chemical reactors, combustion, evapora...

MN 551 Midterm Exam 2023/2024 Saved A patient is experiencing impaired circulation secondary to increased systemic arterial pressure. Which of the following statements is the most relevant phenomenon? Question 1 options: Increased preload due to vascular resistance High afterload because of backpressure against the left ventricle Impaired contractility due to aortic resistance Systolic impairment because of arterial stenosis Question 2 (2 points) Saved A nurse practitioner employe...

ATSC 113 Final question and answers already passed 2024VFR vs MVFR vs IFR - correct answer VFR: mostly by looking out the window, need good vis, stay out of cloud. "VFR over top" when cloud below and clear air. MVFR: poor vis, low cloud, but VFR allowed. IFR: bad weather, stay out of TS, volcanic ash, supercooled cloud & raindrops. Ceiling - correct answer alt of lowest cloud base with cloud coverage ≥ 5 oktas below 20000ft/6km Cloud Coverage - correct answer Clear (0 oktas) - Few...

You are auscultating Jon's chest. When he sits up and leans forward, you can hear a high pitched, blowing murmur at S2. What does this type of murmur most likely indicate? a. Mitral stenosis b. Aortic Stenosis c. Mitral regurgitation d. Aortic regurgitation correct answer: d. Aortic regurgitation Aortic regurg is soft, high pitched, blowing diastolic decrescendo that best heard at the 3rd left interspace at base. Murmur initiated w/ S2 and heard when Pt sits up and leans forward. M...

Typical shapes of unstructured grid cells used in 2D grids are quadrilateral and ______________________ correct answer: triangular a grid is ___________ if any line connecting centers of neighboring cells face between the cells correct answer: orthogonal one disadvantage of using unstructured grids is slower _____________ correct answer: convergence it is recommended for flows with attached boundary layers that the grid includes a layer of thin quadrilateral or hexahedral cells adjac...

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answers A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known...
