The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. calculate the number of kilograms of hydrogen that pass per hour page 2 of 3 through a 6 mm thick sheet of palladium having an area of 0.25 m2 at 600°c. assume a diffusion coefficient of 1.7 × 10-8 m2 /s, that the concentrations at the high and low pressure sides of the plates are 2.0 and 0.4 kg/m3 of hydrogen per cubic meter of palladium, and that steady state conditions have been attained.

0.00408 Kg/h

Explanation:

Change in length is given by

where and is position at higher and lower concentration respectively

Therefore, substituting the figures

Change in concentration is given by

Using the equation

we obtain

1

explanation:

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
