Flanged openings

This solution gives unequivocally the effective control range of both unflanged and flanged openings when the exhaust flow rate and velocity of the idealized cross-draft are known. The distance from the hood opening to the dividing streamline for a hood in uniform flow perpendicular to its axis is thus... [Pg.841]

Circular Flanged Openings- This velocity field has a circular symmetry and it suffices to calculate the velocity directed into the opening ... [Pg.842]

Rectangular Flanged Openings- C i Jhe velocity fields for these openings must be calculated for each direction individually. Here and are the nondimensional velocities parallel to rhe opening plane and v. is the nondimensional velocity perpendicular to the opening plane directed toward the opening plane ... [Pg.842]

The pressure loss associated with this type of exhaust opening is the sum of two pressure losses. The slot hood is usually thought of as a sharp-edged orifice and the duct entry (from the slot plenum) is a flanged opening. The rec ommended hood entry loss is given by Eq. (10.56) - ... [Pg.850]

Flanged openings shall be provided with metal closures at least 5 mm (0.19 in.) thick, with elastomer gaskets and at least four full diameter bolts. For studded openings, all nuts needed for the intended service shall be used to secure closures. [Pg.55]

Example 25-5 A flanged opening rectangular hood (W=4 in. and L = 16 in.) is placed 6 in. from a contaminant source. The process releases the contaminant at low velocity into moderately stiU air. [Pg.365]

The author has only been involved with two proof tests. One had a very large round flanged opening in a 2 1 SE head, offset from the vessel centerline, that resulted in significant loss of strucmral integrity of the head. Normal Code reinforcement methods were inadequate to replace the loss of rigidity of the head. [Pg.734]
