i wanted to know if the flow in the exhaust pipe of an ic engine cross the sonic speed? i have been seeing a lot of papers presented about the supersonic internal flows on the net and hence i wanted to know some of the practical situations where such flows can be seen?
but what is the use of a floating or separating piston in a monotube shock absorber when u can use a plastic bag of nitrogen between the inner and outer tubes??
nitrogen gas is said to prevent cavitation in shock absorbers and thus provide a comfortable ride.. i want to know what actually happens in a shock absorber when nitogen gas is used. how does it prevent cavitation?
disc brakes
i want to know for disc brakes. 100 lbs is a large force! can a person apply that much of force while he is seated on the pedal? i want to know how a person who is about 130 to 150 lbs apply that amount force??
yeah right! but what is the maximum limit upto which u can raise water just using capillarity and without the aid of external energy?? isn't it possible by making a tube of very small diameter??
