F Force

This actually translates into a fairly simple algorithm, based closely on the standard velocity Verlet method. Written in a Fortran-like pseudo-code, it is as follows. At tire start of the run we calculate both rapidly-varying (1) and slowly-varying (F) forces, then, in the main loop ... 

F, = force applied to the object as a function of time V = displacement of the object...

For inlet process fluids above 350°F, forced draft design should be used otherwise, fan failure could subject the fan blades and bearings to excessive temperatures. 

Effluent air temperature should be limited to 220°F to prevent damage to fan blades, bearing, or other mechanical equipment in the hot airstream. When the process inlet temperature exceeds 350°F, forced draft design should be considered because high effluent air temperatures may occur during fan-off or low air flow operations. 

Using the system (9.15-9.17) we determine the distribution of velocity, temperature and pressure within the liquid and vapor domains. We render the equations dimensionless by the following characteristic scales l,o for velocity, 7l,o for temperature, Pl,o for density, Pl,q for pressure, Pl,o Lo f " force and L for length... 

F = force dimension L = length dimension 0 = time dimension M = mass...
