2010-1-1 · Since the kinetic energy of the particles gets larger with the increase of the evaporation temperature, the nuclei possess excess energy and coalesce after collisions. Evaporation temperature is also connected with the vapor pressure. Lower evaporation temperature corresponds to lower vapor pressure, yielding smaller particles . Inert gas type also plays an important role on the particle size.
Get PriceThe boil-off rate of H 2 is typically 0.4%/day for 50 m 3 tanks, 0.2% for 100 m 3 tanks and 0.06% for 20 000 m 3 tanks (using double-walled vacuum-insulated spherical Dewars). Loss of hydrogen due to boil-off is a problem, although recent work indicates that for the most recent tank designs, venting occurs only in the case of infrequent driving.
