What do you mean by mean effective pressure?
What do you mean by mean effective pressure? The mean effective pressure is a quantity relating to the operation of a reciprocating engine and is a valuable measure of an engine’s capacity to do work that is independent of engine displacement.

Is it better to weld uphill or downhill?
Is it better to weld uphill or downhill? In downhill welding, you weld from the top down. Uphill is considered stronger, but as it takes longer, the potential for burn through is greater. It is better for thicker steels, where downhill is adequate for thinner steels. Both techniques require practice, but can produce a good […]

Why are fluids incompressible?
Why are fluids incompressible? Liquids are always considered to be incompressible fluids, as density changes caused by pressure and temperature are small. While intuitively gases may always seem to be incompressible fluids if the gas is permitted to move, a gas can be treated as being incompressible if its change in density is small./span> What […]
