A major artery with 10 mm cross-sectional diameter branches into 16 smaller arteries each of cross-sectional diameter 6 mm. By what factor is the speed of blood flow reduced when it passes into the branches?
1. What is the difference between cross-sectional and time-series ratio analysis? What is benchmarking? 2. When performing cross-sectional ratio analysis, the analyst should pay primary attention to what types of deviations from the norm? Why? 3. Why is it preferable to compare ratios calculated using financial statements that are dated at the same point in time during the year?
Determine the ratio between the cross-sectional areas of two blood vessels, assuming that the voltage ratio induced in identical magnetic flow probes is equal to 2:4 and the ratio of blood flows velocity through these vessels is 3:7. (Hint: the blood flow velocity V = (B) ∗ (L) ∗ (u), V is the voltage measured by the electrodes l is the diameter of the blood vessel B is the magnitude of the magnetic field. The electrodes, magnetic field and the...
A Nozzle is formed so that its cross-sectional area converges linearly along its length. The inside diameters are 75 mm at inlet and 25 mm at the exit respectively and the length of the nozzle is 300 mm. What is the convective acceleration at a section halfway along the length of the nozzle if the discharge is constant at 0.014 m^3/s?
