Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.

An air–fuel mixture is compressed by a piston in a cylinder of an internal combustion engine. The origin of coordinate y is at the top of the cylinder, and y points straight down as shown. The piston is assumed to move up at constant speed VP. The distance L between the top of the cylinder and the piston decreases with time according to the linear approximation L = Lbottom − VPt, where Lbottom is the location of the piston when it is at the bottom of its cycle at time t = 0, as sketched in Fig. At t = 0, the density of the air–fuel mixture in the cylinder is everywhere equal to ?(0). Estimate the density of the air–fuel mixture as a function of time and the given parameters during the piston’s up stroke.
