Per stirpes receive one-third (all of "D"s one-third share). Under "per capita", the two-thirds remaining after "C" 's one-third share was taken would be divided equally among all three children of "B" and "D". (Two-thirds = six ninths) Each would receive two-ninths: "B1", "B2", and "D1" would all receive two-ninths. "Notes:" In many U.S. states, such as New York, a statute has modified the "per stirpes" approach and utilizes instead a per capita with representation approach (also known as modern American per stirpes). Under the per capita with representation approach, the number of branches is determined by reference to the generation nearest
Air changes per hour the airflow efficiency of the enclosure and the methods used to ventilate it. The actual amount of air changed in a well mixed ventilation scenario will be 63.2% after 1 hour and 1 ACH. In order to achieve equilibrium pressure, the amount of air leaving the space and entering the space must be the same. formula_1 Where: Ventilation rates are often expressed as a volume rate per person (CFM per person, L/s per person). The conversion between air changes per hour and ventilation rate per person is as follows: formula_2 Where: Air change rates are often used as rules of
