As shown in Fig 3B, M1 was seated, measuring 134.62 centimeters tall, at one far end of the table. The length of the table was 306.07 centimeters.
It's difficult because the study found that the fine mist created by the cough can stay in the air within that two-metre area for up to three minutes after it was released. What's more, the fine droplets continue to travel beyond the area at a speed of about 200 millimetres a second, or about a kilometre an hour. … Meer weergeven Eric Savory is an engineering professor at Western University who studies fluid mechanics.
