inreasing pressure
50:1 oil mix is typical for outboard two-cycles. Some do a little more in the winter.
Drug peer pressure, peer pressure related with alcohol, sexual peer pressure, and even peer pressure to break the law, are some of the most typical ones.
No, the slave cylinder is a typical hydraulic piston; if the system was 'opened' then the fluid would come out.
Negative pressure switch
Depends on the boat. Aluminum boat, 65-73. Fiberglass, 60-65.
Air pressure, everywhere, varies day to day dependant on weather factors
On the typical train, there is no effort to control pressure above or below a train.
15 psi
800psig.
100-140 psig
A differential cylinder has a large piston that requires a greater amount of oil to displace the cylinder, thus allowing greater uniformity of force than a typical single-acting cylinder.
