Pressure drop across a Attenuator

[SEMPER1]

I have an attenuator size LXWXH 1x1x1m, having splitters of size 100 mm each at a gap of 100 mm, So in total 50% if the effective opening area, Air flow is at 50,000 CFM, Temperature is 55 Degree C, How do I calculate the pressure drop across the attenuator,

Appreciate your inputs

Thanks

Here is an alternative to calculation by looking up silencer with similar size and configuration in this catalog:

Thanks Strong, This will help for sure, If anyone can help with the actual calculation as I'm developing an application for selection of attenuator based on attenuation requirement and pressure drop limits
