Sieve trays with 10% hole area and 0.5 cm diameter holes will be used. Trays are available in standard diameters of 0.25 m increments (0.25,0.50, 0.75, 1, 1.25, 1.50,. .., m). Based on the top tray conditions, determine the required tray diameter rounded up to the nearest larger standard size. Assume a tray spacing of 0.5 m, a foaming factor of 0.80, and a fraction of flood of 0.80. The liquid density is given as 730 kg/m and the vapor density may be estimated based on the ideal gas equation. The liquid surface tension is 27 dynes/cm. 

Standard practice for Brinell testing is to measure the diameter of each indentation twice and average the measurement before entering the tables to determine HBN. The same averaging principle is appHed on nonflat (curved) surfaces which yield an ediptical, not a round, indentation. 

Round this to the nearest standard pipe size. Recalculate V based on actual internal diameter of the line. 

Pipe diameters are rounded up to the next standard size, and proper wall thickness (schedule) is determined consistent with the operating pressure of that portion of the system. For the rate factor, see Figure 13-15. 

This needs to be rounded to the next largest standard pipe diameter of internal diameter 0.154 m. 

Inasmuch as all samples were perfectly round 47 mm disks before "dry" autoclaving, the standard deviation of the measured diameters after autoclaving is a measure of ellipticity,/.e. uneven shrinkage in machine and transverse directions. 

These guidelines can be extended to account for other tablet properties. For instance, based on experience gained in divisible tablets, a case can be made to restrict scoring of standard concave, round tablets to diameters of 9 mm and above, whereas flat-faced, round tablets can be successfully scored to diameters of 7 mm and larger. 

Bubble-cap assemblies in the form of round bell caps are commonly used with diameters ranging from 4 to 7 in. A 6-in.-diameter cap with a 4-in.-diameter riser is a standard size used in many industrial operations. Cap diameters as large as 8 in. have been employed successfully in some operations, and 3-in. caps with 2-in. risers are used in many vacuum towers. Tunnel caps are ordinarily 3 to 6 in. wide and 12 or more in. long. Comparison of the two types shows that tunnel caps have the advantage of a smaller number of units for installation for a given slot and riser area, but the round caps are more... 

Related Calculations. To accommodate standard rotary distributor mechanisms, the diameters of the two filters should be rounded to the nearest 1.5 m (5 ft). To reduce construction costs, the two trickling filters are often made the same size. Where two filters of equal diameter are used, the removal efficiencies will be unequal. In many cases, the hydraulic loading rate will be limited by state standards. 

MUk protein standardizatiop (concentration of pasteurized skimmed milk). Milk protein standardization is designed to maintain the protein level in the milk constant all year round for automated cheese making. It basically involves concentration of pasteurized skimmed milk. It has been one of the major commercial successes in using inorganic membranes for food applications. In commercial production, microfiltration alpha-alumina and zirconia membranes with a pore diameter of 0.1 to 0.7 pm (mostly 0.2 pm) are used. Skimmed milk pasteurized at 70 C is typically concentrated to a volume concentration factor of 2 to 5 [Attia et al., 1988 van der Horst et al., 1994]. The volume concentration factor is the ratio of the initial feed volume to the retentate volume. Thus the higher the factor is, the more concentrated the product becomes. 

The ASME Boiler and Pressure Vessel Code, Division VIII, Section 1, Paragraph UG-81 permits an out of roundness maximum of 1% variation of all diameters from the nominal diameter. This is not sufficient to assure a satisfactory CRM lining. A German standard DIN 28050, Section 4 (10.54 issue) specifies that the roundness shall be determined by measuring the radians and that the radians must not vary more than +0.4% from the average value in the cylindrical part of the apparatus to be CRM lined after final erection. 

Since standardized pipelines are generally used in plants, the calculated values are rounded up to the next available standardized nominal diameter. Standardized nominal diameters are 15, 25,40,50,80,100,150,250, 300 mm, etc. In miniplants nominal diameters of 2, 4, 6,10 mm are typical. The corresponding pressure drop is calculated with Equation (2.4-17) ...
