    Pipe Flow (Sudden Contraction)

    Hi all! I have a problem with my calculations. A customer has a boiler operating @ 1385 psi. For blowdown (to atmospheric tank) they intend to open a valve on a line attached to the boiler (connected to blowdown tank) and I'm trying to calculate the maximum flow possible through the 1.5&quot...

    Allowable Stress

    Can someone explain to me how the allowable axial stress for a W shape column (being used as a support leg ~ 24" high) is determined? I have two differnt (or maybe the same?) ways, but am not sure which to use. AISC has a table that depends on the value of (K1*L/r). There is a table...

    Anchor bolt design / "effective bearing length" meaning & calculat

    I am trying to verify some equations relating to the design of anchor bolts on the saddle of a horizontal vessel in a seismic / wind load design situation. My understanding is that anchor bolt design is governed by one of three load cases including: longitudinal load, shear load, and...

    Bending stress in horizontal pressure vessel saddle base plate

    I am looking for a correct formula for the bending stress in the saddle base plate of a horizontal pressure vessel. The current formula I have has incorrect units. fb = [(6*M)/(tb^2)] is the formula I'm using (units of lb/in instead is lb/in^2), where fb = bending stress, M = bending moment...

    Pressure Vessel Lug Design

    I am trying to follow the Pressure Vessel Design Manual's (by Dennis R. Moss) proceedure for the design of lug supports. I have run into a units proplem, however. The equation for the uniform load on base plate (w) has the wrong units. In the notation (nomenclature) section, (w) is stated to...
