How to calculate effective pump flow-rate across a filter?

[QUOTE="russ_watters, post: 6062376, member: 142"] Welcome to PF! And thanks for including the sketch - too often we don't get them. A few questions: 1. What is the inlet flow rate? 2. You call this a "pump", not a fan; is it pressurized at the outlet? To what pressure? 3. What is the outlet connected to? Are there restrictions there? 4. Is this a factory provided inlet filtration system? Typically the inlet filter and pipe on an air compressor are sized by the factory to be large enough not to provide a "significant" flow restriction. But if they do not, or if you want to check, you can probably calculate it. The filter should have an acutal performance specification you can get from the manufacturer: a specified pressure drop at a specified flow rate or range (curve). The pipe is short so there shouldn't be much static pressure drop along its length, but you can calculate drop through the assembly based on velocity pressure and orifice/fitting losses. Let's start with the clarifications first though because they will affect the methodology... [/QUOTE]
