8. Explain the working principle of a Venturi meter State three applications of Venturi meter Mention two applications of Bernoulli's principle. The pulmonary artery, which connects the heart to the lungs has an inner radius of 2.6 mm and is 8.5 cm long. If the pressure drop between the heart and the lungs is 3x10³ Nm-², what is the average speed of blood in the pulmonary artery. Determine volume flow rate of blood. Assume body temperature of 37° C, and the coefficient of viscosity of blood = 4.0x10-3Nm -2 at 37°C.

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
