Nozzle diameter

Fig. 7. Vessel support and arrangement where d = nozzle diameter, D = vessel diameter, and L = length. Saddles can be straight or tapered. Single supports can be used for small dmms. Combining dmms saves the number of necessary supports (7).

A transition region that extends to about 8 nozzle diameters. [Pg.646]

Several references quote a length of 100 nozzle diameters for the length of the estabhshed flow region. However, this length is dependent on initial velocity and Reynolds number. [Pg.647]

J. Vapor Feed. The vapor inlet nozzle centerline should be at least one nozzle diameter plus 12 in. below the support plate. ... [Pg.85]

K. Reboiler Return. The top of the reboiler return nozzle should be at least one nozzle diameter plus 12 in. (18 in. minimum) below the bed support. The bottom of the reboiler return nozzle should be 12in. minimum above the high liquid level and at least one nozzle diameter (18in. minimum) above the normal liquid level. ... [Pg.85]

Nozzle Diameter, d Nozzle exit diameter will be equal to or less than the diameter of the line feeding the tank. For a known flow rate of fluid supplied to the jet, the diameter is set by the largest size that will satisfy the requirement that the jet be turbulent or will satisfy the nozzle discharge velocity requirement (if the jet is denser than the tank liquid). For a turbulent flow requirement (both heavy and light jets) ... [Pg.470]

If the calculated blending time is longer than desired, nozzle discharge flow rate can be increased or, nozzle diameter increased. Consideration of nozzle recirculation line pressure drops and pump characteristics is required to select the parameter to change. [Pg.471]

Water phase out. Perforated baffle, set min. 6" off bottom, 2 to 3 times nozzle diameter... [Pg.243]

The vessel nozzle diameter (inside) or net free area for relief of vapors through a rupture disk for the usual process applications is calculated in the same manner as for a safety relief valve, except that the nozzle coefficient is 0.62 for vapors and liquids. Most applications in this category are derived from predictable situations where the flow rates, pressures and temperatures can be established with a reasonable degree of certainty. [Pg.455]

The hydraulic equivalent diameter is related to the actual nozzle diameters by... [Pg.899]

Nozzle diameters are usually in 32nds of an inch. Thus, if the bit has three nozzles with of an inch diameter, then... [Pg.899]

The best fit of velocity exponent n in Hp °c ug (Figure 4.3.11) for pure propane (n-butane) is n = 4.733 (3.638), corresponding to Sc = 1.37 (1.61) from n = (2Sc-l)/ (Sc -1), which agreed well with the suggested value of Sc = 1.376 (1.524). The experimental liftoff height data are shown in Figure 4.3.12 for various nozzle diameters and partial air dilutions to fuel [53]. It can be observed that the air dilution to fuel does not alter Ypst and S° sf The results substantiated the role of tri-brachial flames on flame stabilization in laminar jets. As mentioned previously. Equation 4.3.5 limits the maximum velocity Ug for Sc > 1, which corresponds to blowout condition. [Pg.62]

In this equation Uq is the nozzle exit velocity and d is the nozzle diameter. [Pg.48]

In terms of shear stress levels in the developed flow field, the maximum stress [131] occurs at an axial distance between 6 and 7 nozzle diameters downstream and is given by ... [Pg.156]

The size of liquid droplets produced by a spray nozzle depends upon the nozzle diameter, the fluid velocity, and the fluid properties (which may, under some circumstances, include surface tension). [Pg.49]
