Hello, I'm trying to find an equation that models the static and dynamic friction of a reciprocating (Note: NOT rotating) lubricated plunger. I'm just interested in the friction caused by the plunger and not the back pressure from its pumping action. This would involve thin film lubrication I...
Contrary to the manufacturers recommendation why can't I top up an older Pb acid battery with concentrated sulphuric acid, rather than just using distilled water or even the standard 33.53% H2SO4 ("battery acid"), as the electrolyte level lowers? One of the major problems with older batteries is...
Can anyone explain the chemistry behind battery conditioner products like INOX that supposedly reduce sulphation? Their main constituent is Cadmium Sulphate, how does this reduce lead sulphate crystals from forming? The overall Pb acid reaction is:
PbO2 + Pb + 2H2SO4 <-> 2PbSO4 + 2H2O (2.041 V)...
Hi,
I need to install some electronic sensing equipment to the wheel hub of various vehicles from a small car to a BW truck using the existing hub nuts/lugs. To determine how strong to make the casing and its mount I need to know approximately what sort of radial acceleration or g force, ie...
