If we take the gas chamber with 210 m² floor space, and assume that every 1,5 seconds a person's front door, takes the gas chamber filling 210m ² * 10 P / m * 1.5 s / P = 3150 s. On average, the gas chamber during the filling time with 5 P / m² or occupied during the half-filling time with 10 people. read more
