how to calculate packing efficiency

(FCC arrangement) We have found that for a ccp arrangement We also know that, per unit cell in ccp arrangement has effectively 4 spheres. Therefore, Percentage efficiency ..

We have discussed earlier that in both type of close packing (hcp and ccp) approximately amount of the available volume is occupied by spheres (atom..

M.A., V.R. and efficiency have no units as they are ratios between similar quantiti..

Current Efficiency - In many industrial processes, the process of electrolysis is less efficient than expected from the Faraday's laws. The amount of material obtained during electrolysis is generally less than that expected due to: Loss of energy during its flow through the sys..

In amplitude modulation, the sidebands contain the signal. The power in the sidebands is the only useful power. The power carrier by the side bands is only 33.3% even when there is 100% modulation. If modulation is 50%, then power carried by the sidebands is 11.1%. Clearly, the useful power is sma..

Hexagonal close packing is the most efficient two dimensional close packing. Let us now consider a three dimensional packing keeping a hexagonal close packed pattern for layers. Two types of arrangements are possible. a) Hexagonal close packin..

Let, The mass of the organic compound taken be = W g Increase in the mass of magnesium perchlorate tube = W 1 g Increase in the mass of the KOH tube = W 2 g So, Mass of water formed = W 1 g Mass of carbon dioxide formed = W 2 g ..

Let, The mass of the organic compound be = W g Mass of the precipitate of BaSO 4 = W 1 g From stoichiometry, BaSO 4 = S 1 mol 1 mol 1 molecular mass 1 atomic mass 233 g 32 g Therefore, ..

Let, The mass of silver salt taken for ignition be = W g Mass of silver left behind after ignition = W 1 g We have RCOOAg = Ag1 equivalent 1 equivalent The equivalent mass of silver is 108. Hence, the mass of silver salt that would leave 108 g of residue (equivalent mass of the silver) i..

Let, The mass of the organic compound taken be = W g Volume of air displaced = V 1 mL Atmospheric pressure = P mm of Hg Room temperature, T 1 = t o C = (t + 273)K Aqueous tension at t o C = p mm of Hg Pressure of the dry air, P 1 = (P-p) mm Hg ..
