    Feed pipe design for gentle flow down the wall of a tank

    Related to thread378-239797, I'm interested in design criteria for designing a feed pipe that directs a top-fed fluid onto the inside wall of a tank. If the velocity in the feed pipe is at most 1 m/s to limit static charge generation, how do I ensure that the fluid then flows gently down the...

    Failed Regulator Characteristic for Relief Sizing

    When sizing a relief valve for a failed regulator scenario, what is typically done to determine what the "failed" characteristic of the regulator is? I'm finding it difficult to get a vendor/manufacturer to tell me a "fail Cv" for their regulator, or even what the internal orifice diameter is...

    Can increasing backpressure increase the flow of a flashing liquid?

    Suppose there's a pipe connecting two vessels that is very long relative to its diameter, and there is a pressure differential between the tanks driving the flow of liquid through the pipe. Now suppose that somewhere along the length of this pipe the pressure-drop causes the fluid to flash...
