discharge velocity मीनिंग इन हिंदी

Lower discharge velocity means lower noise levels and, in the case of variable air volume ( VAV ) air conditioning systems, permits greater turndown ratios.
Each diffuser has a head consisting of four duck bill valves that assist in maintaining high discharge velocity for optimum mixing, independent of plant operating conditions.
Because the Coand effect causes air discharged from the diffuser to " stick " to the ceiling, it travels farther before dropping for the same discharge velocity than it would if the diffuser was mounted in free air, without the neighbouring ceiling.
