Wherever persons can be in contact with electricity with voltage above 60 volts, the salty fluids inside their bodies can become a...

I wrote a program to do brute force counting and its answer matches that of @bob012345 in post #15. I have not thoroughly examined the...

Happy New Year @Lnewqban! Yes, I see what you mean. So, for example, with A remaining pinned and with B free to move horizontally, the...

Happy New Year, Steve! It seems to me that, due to joints C and G, if any of the pinned-supports is replaced by a simple horizontal...

If you are normally swimming, your ears feel atmospheric pressure only. If you then are diving at a depth of 10 meter under the surface...

The height difference should not have any sign. The lesser height reached by its liquid column is the effect caused by the lower...

Copied from the OP: "... and the water supply line (ppr pipe) are underground, below the earth in the garden". Unless I am missing it...

The piston pump valve requires a pressure difference to lift it. That pressure drop reduces the depth of the vacuum that can be pulled...

A piston pump needs valves, a gear pump does not. If the valves are spring loaded, one way check valves, they will reduce the vacuum you...

I think that misses a triangle 1-24-20, for example, IIUC (see image in #2 above.)

And 1-7-24 as well.

This still could trip an RCD depending on the path of the current on the water pipe. The pipe from the house to the shutoff valve may be...

Is there any grounding for the water contained in the plastic pipes system? Could the grounding of the water heater be considered a...

So piston pumps did much better than gear pumps but using piston pumps for modern engines seem to be a little bit of overkill based on...
