How do you imagine momentum?
The mass has a fundamental property and that is like a battery that can be filled with the charge and become a container of energy, mass by virtue of its inertia can accept the work of a force F ...

How do you imagine momentum?
@JonathonRSwift provided a good analogy for momentum using a rugby player or a child running at and into you. The rugby player would likely bowl you over while a child even moving at twice the speed ...

Weight Sensing Problem: Need to detect 10kg load down to milligram accuracy
Actually, 600mL of liquid (water?) is about 600g, not 10kg, so it makes selecting an off-the-shelf balance a lot easier. Likewise, 2ul is about 2mg so a 1mg accuracy should be good enough. Based on ...

Precision measurement of liquid levels
I believe some laser equipment does have the 20µm that you are looking for:
Displacement measurement sensors
This product for example has a 20µm precision, but it is said that the precision depends ...

Optimized water droplet formation
There is research on the impact of water droplets on deep liquids and solid surfaces.
It seems the most significant factor in the outcome of the collision and its rather short span, in the range of a ...

Reusable 100um x 5mm flow chamber
I believe there are 3 mainly options for this case:
use microfluidic devices that are made to be reusable;
use microfluidic devices that are not are not meant to be reusable but cheaper;
devise a ...

How do you imagine momentum?
Momentum is a way we can measure mass that is in motion. Any object that is moving has momentum.
The momentum $p$ of an object is equal to the mass $m$ times the velocity $v$.
$$\vec{p} = m \cdot \vec{...

CFD simulation of an Air and Oxygen gas gradient in a microfluidics device
I've decided to go with ANSYS student edition to do the CFD
simulation and Autodesk Fusion360 to model the part (microfluidics
device), as the part is very simple just a box with two holes in it.
...

How can I confirm nL Volume Measurement for Pump and Sensor Calibration
This is a challenging measurement. In my opinion best done with a very good balance. Fully shielded from thermals and vibration, obviously. Use a small container with small opening diameter to limit ...

Pushing fluid through microfluidics
yes. knowing the surface tension of the fluid and its contact angle with the channel walls, you can select a channel width that does not support two-phase flow, where bubbles and fluid can pass by one ...
