ahmm.. we found some info in the net and they make a paper from feather by milling the feather, then macerating it by 10 grams of commercial glue and 500 ml water, and putting some ethanol.. that's how they pulp the feathers.. will it work for our filter paper?
feathers have the same properties as wool.. i am planning to make filter paper out of feathers but i have no idea of what process to be used.. kraft pulping process are for woods.. how about nonwood?.. anyone who are expert in pulping process can help me.. thanks!
i was thinking of a good thesis topic involving enviro-friendly touch and i came up with this: plastic photodegrador! the concept was from the idea that plastic degrades easily in the ocean, so i am planning to design an equipment that will make plastics degrade fast. the design is somehow like...
i prepared a setup wherein i heat a nichrome wire with 3 volts battery, measure its power, the temperature of the nichrome and the temperature of air.. by using the formula
ΔT=PRsurf
where
ΔT=Tnichrome - Tair
P=VI
Rsurf=1/hA,
R is, basically, the thermal resistance to heat...
if time is removed from the equation Q=VxIxt, will it still be valid to be an equation of energy?
i need that equation to estimate the heat transfer coefficient of a nichrome wire heated using direct current,but putting time to the equation makes everything complicated..
(i'd read someone's...
thanks for the replies..
@Integral- i bought the nichrome wire with its wattage already set..
@sophiecentaur- i can't find a 24W nichrome wire.. suppose i cut the 800W nichrome wire, will that reduce the wattage?..
i just want to heat the nichrome wire using direct current to compute the temperature it can produce and not to heat something.. my problem is a safe setup of heating the 800watts nihrome wire using DC..
hi guys.. I'm new here and this is my first post.. my friends told me that the title of this post is impossible and i need a car battery to heat the 800W nichrome wire, and i believe them.. they also said that AC will solve the problem.. but i need to use DC so i came up with using diodes.. the...
