Steady flow equation - Study guides, Class notes & Summaries

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...

CBE Final The heat conduction equation in a medium is given in the simplest form as: ∂^2T ∂^2T =0 ∂x^2 + ∂y^2 where the parameters have their usual meaning. Which of the following statements is incorrect - correct answer Thermal conductivity is negligible If force, length, and time are selected as the three fundamental dimensions, the units of viscosity in the SI system could be written as - correct answer kg/m*s The thermal conductivity of a substance may be defined as the ...

3D gradient echo axial views can be used in cervical spine imaging to provide - Thin, contiguous sections of the spine, the ability to reformat into any other imaging plane, retrospectively, the ability to get either T1, spin density or T2* information by changing parameters. In complete spine imaging, to rule out metastatic lesions of the spinal cord, contrast enhancement can be used with T1 weighted images because - metastatic lesions enhance and normal cord does not Due to the difference...

In MRI, substances respond to a specific radio frequency which is known as: - Resonance frequency The effects of main magnetic field inhomogeneities on the FID signal are corrected for in a Spin-echo sequence by applying a second radio-frequency pulse. The flip angle of this radio-frequency pulse is: - 180 degrees The components of the Gyro-magnetic ratio are: - Magnetic moment to angular momentum Which type of electromagnetic coils produce smaller magnetic field which allow spatial locali...

The four things needed for good SI - limited distortion limited feedback Direct signal which is louder than competing sound Direct signal to audience in reverberant room Elements of electronic sound systems - microphone, amplifier, electronic controls, and loudspeaker Central sound system - cluster of speakers over sound source Distributed sound system - An array of speakers all over the room Seat integrated sound system - has speakers built into the seats Microphone - A device that con...

Blood Distribution at Rest - Brain: 13%, 720 mL Muscle: 21% 1200 mL Skin: 8.5%, 500 mL Kidneys: 19%, 1100 mL Abdomen: 24%, 1400 mL Heart: 4%, 250 mL If you measure systolic blood pressure, when would it be highest, standing, sitting or lying down? - standing Systolic pressure - It is the maximum pressure your heart exerts while beating Diastolic pressure - The pressure in the arteries when the heart is at rest If you measure systolic, when would it be lowest, standing, sitting or lying...
