Fuel Oils Viscosities - Engineering ToolBox

Saybolt Universal Seconds - SSU - viscosity versus temperature for typical fuel oils: T F = T C 9 / 5 + 32; SSU (Saybolt Universal Seconds) = centiStokes (cSt) x 4.55 1); 4 - 5000 SSU is the maximum practical limit for pumping; 150 - 300 SSU is the atomization range fuel oil no. 5 and 6; 1) Note that this equation is correct only for a range of viscosities. There is no linear relationship

Steam engine - Wikipedia

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.The term "steam engine" is generally applied only to reciprocating engines as just

Pulsejet - Wikipedia

A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses.A pulsejet engine can be made with few or no moving parts, and is capable of running statically (i.e. it does not need to have air forced into its inlet, typically by forward motion).. Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give
