If time permits and a more accurate estimate is desired, particularly if the compressor is intercooled or has sidestreams, the velocity head losses through the nozzles can be estimated using the values from Table 2-2. This is possible where the nozzle sizes are available or can readily be estimated. When coolers are involved, the drop through the cooler should be included. Subtract the pressure drop from the inlet pressure (of the stage following the element) and recalculate a modified pressure ratio for the section. The cooler pressure drop can be approximated by using 2 - i... [Pg.164]

A full opening valve or variable orifice should be able to restrict flows of liquid into the bottom of the reboUer so that the instability in the liquid in the column will not be direcdy introduced into the inlet of the reboUer. Generally, the liquid inlet nozzle size should be about 50% in the inlet tube flow cross-section area. A large line is sometimes used, but a restricting provision should be provided to to stabilize operations. [Pg.204]

Optimal hydraulics is the proper balance of hydraulic parameters (flowrate and equivalent nozzle size) that satisfy chosen criteria of optimization. Hydraulic quantities used to characterize jet bit performance include hydraulic horsepower, jet impact force, jet velocity, Reynolds number at the nozzle, generalized drilling rate or cost per foot drilled. While designing the hydraulic program the limitations due to cuttings transport in the annulus and pump performance characteristics must be included. [Pg.1097]

Nozzle size at flowrate test is 3 x -H. The minimum required flowrate is 350 gal/min. [Pg.1099]

Note 4 Surface preparation for painting is often analysed separately as it may typically form one-third of the total cost. Poor surface preparation can more than halve the life expectancy of a coating (and add over 100% to the total life cost) but save less than 20% of the total capital cost. Correct choice of blasting equipment (e.g. nozzle size, grade of abrasive) can save up to half the surface preparation cost. [Pg.1386]

The bubbling frequencies measured in this study are much smaller than the 5- 8 Hz measured by Rowe et al. (1979) and the 20 Hz measured by Hsiung and Grace (1978). The difference may be due to the dominant effect of the much larger initial bed heights and jet nozzle sizes in this study. [Pg.279]
