Then we can easily determine the dynamic reduction to the air which turns into the bend. For this we use a similar formulation as prior to. Velocity out didived by velocity in to seek out our velocity ratio.

many thanks lots for this excellent work. May well you are doing much more lessons similar to this sequence on BMS, SCADA, DCS and its interaction with HVAC systems from the smart properties.
