when we brn the fuels containing hydrogen,it will react with the oxygen in the air and produce steam.if we condense this steam,it will release some amount of heat.this heat is called latent heat of condensation.so in addition to the normal amount of heat liberated on burning,latent heat is also added .thus there is increase in the amount of heat.this is called higher calorific value or gross calorific value..
instead of condensing the steam if we are allowing it to let it go,there will be no latent heat of condensation.so on comparing it to the gross calorific value,its amount of heat will be less.this is called lower calorific value or net calorific value..
so, L.C.V = H.C.V - Latent heat of condensation.
It varies based on the type and grade of coal. The heat value is less for bituminous than for anthracite, etc.
A pH value less than 7.0.
The definition of acidic is having a pH less than 7.
less than 0.5
they interact more with the silica gel, thus travel less than non-polar compounds. Resulting in a lower Rf value.
It varies based on the type and grade of coal. The heat value is less for bituminous than for anthracite, etc.
The calorific value of one litre of extra light oil amounts to 10 kWh, as does the calorific value of 1m3 of gas. It is therefore true that: 2kg pellets ~ 1 litre extra light oil ~ 1m3 gas. In terms of price pellets do significantly better than oil and LPG.
A value that is less than zero.A value that is less than zero.A value that is less than zero.A value that is less than zero.
If revenue is less than costs, the gross profit is negative -- it is not a profitable company.
Methane is CH4 and LPG(Butane) is C4H10. The energy in the Carbon Carbon bond (C-C)is more than that in the Carbon Hydrogen bond (C- H). Since there are more number of C-C bonds in butane (LPG) than in methane,calorific value of LPG or butane is higher than that of methane.
Potato chips are deep fried and have high calorific value with more energy than boiled or baked potatoes that have no added hydrocarbons in fried oil.
No.
5. It does not have a value greater than 12. Consequently, it does not have a value greater than 12 and less than 13.
They are the same - except that in "less", something has a value which is less than some implied value - often the current value. For example, "Please can you make less noise?" implies "Please can you make less noise than you are making now?"
The - before the 1 represents it is less, so the -1 will always be less than a, since the - is before the one, and so that means the 1 is less than a.
i think because sometimes anthracite has more ash and vm than bituminous
