Flue gas flow calculation formula

                                              Flue gas flow calculation formula

Q = Sv = constant. For water flow velocity (S for the cross section area, v) (on fluid mechanics with Q = AV), unit is cubic meters per second. Incompressible fluid as a stationary flow, and through the same flow tube of the cross section of flow is constant.

Wet flue gas = * point flow velocity field coefficient of average flow velocity, point velocity = * differential pressure signal/Sqr pitot coefficient (0.6025), coefficient of pitot tube in the pitot tube above the target, can see in the computer system parameter Settings. Differential pressure differential pressure transmitter is 4-20 ma signal measurement, all the way to send CEMS, all the way to send DCS.

Velocity field coefficient is 1, commonly in the computer monitoring system can be seen in the parameter Settings. Differential pressure signal of locale measurement of differential pressure transmitter 4-20 ma value. SQR said prescribing.


The fluid flows within a certain amount of channel flow measurement are collectively referred to as flow measurement. Flow measurement of the fluid is diversified, such as the measuring objects are gas, liquid and mixed fluid; Fluid have significant differences in temperature, pressure, flow rate, the requirements of the measurement accuracy is also each are not identical.

As a result, the flow measurement task is according to the measurement, the measurement of body type, flow state, as well as places for measuring measurement condition, research the corresponding measurement method, and to ensure that the correct flow quantity.
