Question
Please write neat and clear, and explain each step, thanks!

4.32. We repeat the previous experiment, but now we use a tube to measure the total pressure, as shown in the figure. If the water-column height in the manome- ter h 8 cm, calculate the velocity at the test section (Pwater 1000 kg/m3, Pair 1.22 kg/m3) Wind tunnel Water L Problem 4.32.

    Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...

    It's a weak acid strong base titration Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
