    Here k(T) is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the solution. (For a reaction taking place at a boundary one would use instead moles of A or B per unit area.) - For every action there is an equal and opposite reaction • The jet engine's action is accelerating a mass of gas and sending it out tailpipe. • The equal and opposite reaction is thrust. P1, Page 24 The Thrust Equation • Recall from Newton's second law:The above combustion reaction is an example of a stoichiometric mixture, that is, there is just enough oxygen present to chemically react with all the fuel. The highest flame temperature is achieved under these conditions, however it is often desirable to operate a rocket engine at a "fuel-rich" mixture ratio. Although different isotopes of light elements can be paired to achieve fusion, the deuterium-tritium (DT) reaction has been identified as the most efficient for fusion devices.

    A vent silencer is a device that is intended to reduce the noise levels created when high-pressure gas or steam is expanded to the atmosphere. This noise is produced by the rapid turbulence of the mixing gas jet and energy release of the compressed gas. Most of the noise occurs at the expansion across the valve and is emitted at the stack opening.
