1. Estimation of the power required for conveying bulk solids dilute phase

The power can be calculated with the following estimation :

Blower power requirement dilute phase pneumatic conveying

Please note that this formula is not for design but only to have an idea in pre-project or during troubleshooting. This estimation is valid for systems running in dilute phase.
