    Generic curve for a centrifugal blower

    Hi all, Could anyone get me a generic cappacity v.s. head curve for two centrifugal air blowers. An experimental correlation would be of great help to me. The first blower I need it for has a working point at 14500 m3/hr with diff. head 8.96 kPa, 60 kw motor. The type is MAEB 400-v according...

    Minimum flow over Carbonbed adsorber

    Weve got an adsorber for VOC's in tank ofgas, nothing special. I want to raise the caloric value for a downstream RTO by (partially) bypassing the adsorber. During normal operation, the flow of air and vapour through the carbon helps to remove heat by convection. I was warned that very low air...

    API 2000 or 2557: Vapour treatment flow calculation

    Hi all, Im trying to calculate the amount of vapour expected from several tanks filled with Methanol to size the vapour treatment header. API 2000 does mention thermal outbreathing but i'm in doubt if this is referring to normal flows or sizes to maximum emergency scenarios. Does API 2557...

    Mixing gasses

    Dear all, I've been asked to solve a problem involving fluid dynamics and I wonder if anyone could help me find a way to approach this problem. Situation: Two gasflows of different flow and temperature are mixed using a T-piece. Known or previously calculated values: flows, temperatures of...
