A similar graph from a another discipline is the following
Basically you will need to plot for each test (which I assume had a different d/S), the values of your experiment.
So for each d/S you calculated different values of the convective heat coefficient at different air speeds. So you need to plot 10 different graphs.

First of all, do NOT USE EXCEL. Sooner or later it will lead to undetected errors and great sadness.
Next, whether you use "Excel formulas" or proper code in tools like MATLAB or python, you need to start with the equations and formulas and boundary conditions you want to work with. Only after you have this can you start to make software do the ...

Obviously putting it in series is better than the other two options. Putting in series, means that If you put two (perfectly calibrated) flow meters in series, then you will be able to make inferences on the actual value based on the calibration uncertainty, the reading uncertainty, and the sampling statistics.
Problems with the other setups
I'll start with ...

I will make two assumptions from your question:
horizontal orientation of nozzle + piston in order to discard hydrostatic pressure, since a vertical orientation would modify the force required to move the piston due to the fluid's weight;
the graph showed is obtained by experimental measurements.
We can estimate the Reynolds number $Re=\frac{\rho \frac{Q}{...

This question cannot be answered as it is (without numerical values). The main reason is that you need to determine the pressure Losses due to the pipe length. However the pressure losses are dependent on the type of flow (Laminar or turbulent), which will be dependent on the actual velocity and the roughness in the pipe.
Having said the above, the process ...

Pressurizing oxygen, especially for medical use requires a purpose built compressor. Other compressors add oil that can damage the lungs and catch fire. Oil-less diaphragm compressors are better, but may be damaged by pure oxygen and are also not rated for medical use. Pressurizing oxygen is not a good DIY project. A different solution to consider is to ...

You confused me too, lol. Lets back up.
Water will only condense when moist air is cooled below its dew point. The amount of water the air can store is not important to us in this case; just when it is at the dew point.
This means that in order for this system to produce any water, the night temperature must be less than the noon dew point. The final temp ...

The key principle is that, when expressed in terms of the non-dimensional head coefficient $K_H := gH/\left(D\omega\right)^2$ and the non-dimensional flow coefficient $K_Q := Q/\left(D^3\omega\right)$, there is a single head-flow characteristic for the whole family of geometrically similar pumps. That is to say, when expressed in terms of those quantities, ...

As much math as you can get. Knowing basic chemistry and physics will help. ME physics is strictly newtonian stuff. They'll teach you everything else. Tech tip - get a calculator that changes from polar to cartesian coordinates & statics will be a breeze.
