    627 Regulator - Flow capacity lower at max inlet pressure? Why?

    Hi Everyone, Question: How come for a 627 regulator for example, if we reach the maximum inlet pressure than the trim size can handle, how come the flow capacity at the max inlet pressure is way less than the flow capacity with an inlet pressure that's half the max inlet pressure? Example...

    Estimating how far away a cable rated for 90 C has to be from a stack

    Hello folks, How would you go about estimating how far away a cable rated for 90 C has to be from a stack? This cable is a 4-20 mA signal from a temperature transmitter installed on the stack itself. I thought I would estimate the thermal radiation from the stack using AERflare spreadhseet...

    PSV - Snap Acting - Instantaneous flow greater than blocked flow?

    Hello everyone, I used Korf to simulate a PSV opening at 9300 kPag to estimate the back pressure in the flare line. This PSV protects a separator against blocked flow. The instantaneous flow through the orifice is close to 150 MMSCFD. Yet the blocked flow case for this PSV is only 70MMSCFD...
