Default Fluent cyclone pressure drop

Hello friends. I am trying to calculate the pressure drop and cyclone efficiency with fluent cyclone analysis of the video. I use 1,200,000 hexa mesh in ICEM CFD. Turbulence model RSM model, I use Pressure Velocity Coupling-SIMPLE, Pressure-PRESTO, Momentum-QUICK and Second Order Upwind. I start with the steady solver to drive the flow, and then I use transiet. I calculate the pressure loss too much compared to the experimental data. I could not figure out where I was wrong. I will have some questions .
1 - How is total and static pressure loss calculated ? a or b

a) Surface integral - mass weighted average, Total pressure drop = inlet total pressure - outlet total pressure
b) volume integral mass average, total pressure loss = Total Pressure is Fluid

2 - When the input speed is 12.69m / s, the fluent output speed is calculated more. Since the output area is larger than the input area, the output speed must be smaller than the input speed. Where can the problem be?

Please help me .

i compute the total pressure around 900 pa. how bout you?
did you solve your problem?
