Que les parece para pintar los tambores que llevaremos a AC???

De que color serán?

[martinelterrible]

Los vas a llevar enteros o cortados a lo largo en mitades?

[m606paz]

Enteros...No comprendo la pregunta...

para que usarian tanto metanol???....la napalm se hace con nafta...y para grapa no sirve....

[Patman]

El metanol sera para algo de aviacion?

Los tambores normalmente son verde oliva. Aunque tambien los e visto color arena. El mio lo tengo pintado color arena.

[martinelterrible]

Pat,imagino que eran negros,mira que nam no fue ww2,mucha logistica estuvo en manos de contratistas,como la provision,imagino que los tambores tendrian los colores comerciales en gral,azules,blancos o negros...de todas formas,por norma,el color deberia marcar el contenido,pero vaya a saber uno....para colmo se ven casi todas las fotos B&W

un abrazo

PD,se me ocurre muchas cosas con el metanol...pero en esas cantidades? vaya a saber...

el methanol se utiliza como aditivo en motores de aviacion, tanto jets como a piston, mas en la epoca de esa foto:

It used to be commonplace for large piston engines to require special fluids to increase their take-off power. Similar injection systems are also incorporated in some turbo-jet and turbo-prop engines. The power increase is achieved by cooling the air consumed, to raise its density and thereby increase the weight of air available for combustion. This effect can be obtained by using water alone but it is usual to inject a mixture of methanol and water to produce a greater degree of evaporative cooling and also to provide additional fuel energy.

For piston engines, methanol/water mixtures are used and these may have 1 percent of a corrosion inhibiting oil added. The injection system may be used to compensate for the power lost when operating under high temperature and/or high altitude conditions (i.e. with low air densities) or to obtain increased take-off power under normal atmospheric conditions, by permitting higher boost pressure for a short period.

Both water alone and methanol/water mixtures are used in gas turbine engines, principally to restore the take-off power (or thrust) lost when operating under low air density conditions. Use of a corrosion inhibitor in power boost fluids supplied for these engines is not permitted.

The methanol and water used must be of very high quality to avoid formation of engine deposits. The water must be either demineralised or distilled and the only adulterant permitted in the methanol is up to 0.5 per cent of pyridine if required by local regulations as a de-naturant. In the past there were several different grades of water/methanol mixtures, e.g. 45/55/0 for turbine engines, 50/50/0 for piston engines (this was also available with 1% corrosion inhibiting oil and was designated 50/50/1) and 60/40/0, however, with decreasing demand Shell now only supplies 45/55/0. The table shows the principal characteristics of Shell demineralised water and of the commonly used methanol/water blend.

si pablo,la inyeccion de agua metanol es de ww2,pero....tanto...metanol..

y de los jet, lea lo que puse en ingles:

Gracias pablo por la excelente explicacion!

Podes agregar bajo que condiciones y por que se utilizaba el metanol??
