关于气体流量测量单位标准立方米的意义气体流量测量单位采用标准立方米我们常称为仿质量单位因为它看似体积单位其实为质量单位它与使用地点的压力温度没有任何关系如果气体为天然气标准立方米的质量还与天然气的组分有关在天然气贸易结算计量时采用能量单位比较合理就因为同样的天然气质量如其组分不同则其发热量亦不同。例:空气标准立方米=千克(标准状态为kPa,°C)流量mh(标准状态)=kgh天然气设天然气相对密度d=,则标准立方米=×=kg流量mh(标准状态)=kgh标准状态中压力无论国内外都是标准大气压即kPa但是温度就不尽相同我过有二种温度标准°C°C。天然气用°C煤气用°C或°C这是历史原因造成的。在贸易结算中合同双方可协商用任何一个温度称为合同温度。国际上则采用°C(°F)或°C(°F)。流量计测量出工况体积流量需经压力温度换算(用流量演算器)而得。其换算公式为式中qvnqv分别为标准状态下和工作状态的体积流量mhpnp分别为标准状态下和工作状态的绝对压力PaTnT分别为标准状态下和工作状态的热力学温度KZnZ分别为标准状态下和工作状态的气体压缩系数。<<ASCIIEncodePagesfalseAllowTransparencyfalseAutoPositionEPSFilestrueAutoRotatePagesAllBindingLeftCalGrayProfile(DotGain)CalRGBProfile(AdobeRGB)CalCMYKProfile(JapanColorCoated)sRGBProfile(sRGBIEC)CannotEmbedFontPolicyWarningCompatibilityLevelCompressObjectsTagsCompressPagestrueConvertImagesToIndexedtruePassThroughJPEGImagestrueCreateJDFFilefalseCreateJobTicketfalseDefaultRenderingIntentDefaultDetectBlendstrueDetectCurvesColorConversionStrategyUseDeviceIndependentColorDoThumbnailsfalseEmbedAllFontstrueEmbedOpenTypefalseParseICCProfilesInCommentstrueEmbedJobOptionstrueDSCReportingLevelEmitDSCWarningsfalseEndPageImageMemoryLockDistillerParamsfalseMaxSubsetPctOptimizetrueOPMParseDSCCommentstrueParseDSCCommentsForDocInfotruePreserveCopyPagetruePreserveDICMYKValuestruePreserveEPSInfotruePreserveFlatnesstruePreserveHalftoneInfofalsePreserveOPICommentsfalsePreserveOverprintSettingstrueStartPageSubsetFontstrueTransferFunctionInfoApplyUCRandBGInfoPreserveUseProloguefalseColorSettingsFile(JapanColorPrepress)AlwaysEmbedtrueNeverEmbedtrueAntiAliasColorImagesfalseCropColorImagestrueColorImageMinResolutionColorImageMinResolutionPolicyOKDownsampleColorImagestrueColorImageDownsampleTypeBicubicColorImageResolutionColorImageDepthColorImageMinDownsampleDepthColorImageDownsampleThresholdEncodeColorImagestrueColorImageFilterDCTEncodeAutoFilterColorImagestrueColorImageAutoFilterStrategyJPEGColorACSImageDict<<QFactorHSamplesVSamples>>ColorImageDict<<QFactorHSamplesVSamples>>JPEGColorACSImageDict<<TileWidthTileHeightQuality>>JPEGColorImageDict<<TileWidthTileHeightQuality>>AntiAliasGrayImagesfalseCropGrayImagestrueGrayImageMinResolutionGrayImageMinResolutionPolicyOKDownsampleGrayImagestrueGrayImageDownsampleTypeBicubicGrayImageResolutionGrayImageDepthGrayImageMinDownsampleDepthGrayImageDownsampleThresholdEncodeGrayImagestrueGrayImageFilterDCTEncodeAutoFilterGrayImagestrueGrayImageAutoFilterStrategyJPEGGrayACSImageDict<<QFactorHSamplesVSamples>>GrayImageDict<<QFactorHSamplesVSamples>>JPEGGrayACSImageDict<<TileWidthTileHeightQuality>>JPEGGrayImageDict<<TileWidthTileHeightQuality>>AntiAliasMonoImagesfalseCropMonoImagestrueMonoImageMinResolutionMonoImageMinResolutionPolicyOKDownsampleMonoImagestrueMonoImageDownsampleTypeBicubicMonoImageResolutionMonoImageDepthMonoImageDownsampleThresholdEncodeMonoImagestrueMonoImageFilterCCITTFaxEncodeMonoImageDict<<K>>AllowPSXObjectsfalseCheckComplianceNonePDFXaCheckfalsePDFXCheckfalsePDFXCompliantPDFOnlyfalsePDFXNoTrimBoxErrortruePDFXTrimBoxToMediaBoxOffsetPDFXSetBleedBoxToMediaBoxtruePDFXBleedBoxToTrimBoxOffsetPDFXOutputIntentProfile()PDFXOutputConditionIdentifier()PDFXOutputCondition()PDFXRegistryName()PDFXTrappedFalseDescription<<CHT<FEFFffebadfeefaacbfefefcafcffeafadcceacaefeefffcfeeecafadcfbfdfefaacbef>DAN<FEFFecceecffdfbdecbcbeeccbfbceeeefdfbdebeeefccfefee>DEU<FEFFeeecceeadccefefdfbdeecfeeefbbfdbeeffdeeaedfeeccdfbdebfeeedfefefffeee>ESP<FEFFcfefefdefffedfecedfffdeffeeefdefffefcfefeffe>FRA<FEFFcaffeeefdeffedfeceddeecfdeeeeeafefcefefecee>ITA<FEFFcaadfafefdefedcedeffbfefdeffeffeffefee>JPN<FEFFadcceafabffefcbffeebceabfddcdecbafccddeafbfeeffdebfcdbeeadbafccfdaaebffafeeedbfcde>KOR<FEFFcccccaccadcecbcadcdddbbdbcfadcaecdccacedccbccccdfbbccbcccdbcbeecbaccccbcbbccbfbcffeccccdcccfcccbbcbee>NLD(GebruikdezeinstellingenomAdobePDFdocumententemakenvoorkwaliteitsafdrukkenopdesktopprintersenproofersDegemaaktePDFdocumentenkunnenwordengeopendmetAcrobatenAdobeReaderenhoger)NOR<FEFFbeecceeceffdfbdefbfbcefbccffedfbdeebeeefccfeccee>PTB<FEFFcafeeffdfdeffdfcddfbffffeffdefffdffdffffefffe>SUO<FEFFbeeeeebcbecffdfbdeacbffecfafeecfdfbdefefccafeaccaddcce>SVE<FEFFeeeeeecceeefdccbfdfbdefbcbeecbffbfbebdfbdebefefffefee>ENU(UsethesesettingstocreateAdobePDFdocumentsforqualityprintingondesktopprintersandproofersCreatedPDFdocumentscanbeopenedwithAcrobatandAdobeReaderandlater)CHS<FEFFfffdebbbebabefaefafccacfffdbcaddcfaefeefffcfeeecafadcfbefa>>>Namespace(Adobe)(Common)()OtherNamespaces<<AsReaderSpreadsfalseCropImagesToFramestrueErrorControlWarnAndContinueFlattenerIgnoreSpreadOverridesfalseIncludeGuidesGridsfalseIncludeNonPrintingfalseIncludeSlugfalseNamespace(Adobe)(InDesign)()OmitPlacedBitmapsfalseOmitPlacedEPSfalseOmitPlacedPDFfalseSimulateOverprintLegacy>><<AddBleedMarksfalseAddColorBarsfalseAddCropMarksfalseAddPageInfofalseAddRegMarksfalseConvertColorsNoConversionDestinationProfileName()DestinationProfileSelectorNADownsampleBitImagestrueFlattenerPreset<<PresetSelectorMediumResolution>>FormElementsfalseGenerateStructuretrueIncludeBookmarksfalseIncludeHyperlinksfalse
