过热蒸汽密度.doc

蒸汽的重度随压力和温度的变化而变化（重度：即重力密度，Υ=ρ*g），过热蒸汽在压力为10~160公斤/厘米3，温度为300~555℃的范围内，重度Υ与压力P、温度t的关系可用经验公式：Υ=1.82*P/(t/100+1.66-0.55*P/100)

过热蒸汽密度表表中压力为绝对压力，查表时应按仪表显示压力+大气压。密度单位为kg/m3压力(Mpa)温度（℃）1501701902102300.100.51640.49250.47070.45070.43230.150.77810.74120.70790.67770.65000.201.04230.99180.94660.90560.86840.251.30891.24441.18691.13491.08490.301.57831.49901.42871.36531.30790.402.12372.01411.91661.82971.75130.502.66582.53802.41212.29972.19920.804.39664.16763.93503.74003.53741.106.13135.83325.53425.23564.98101.407.87857.51637.15406.79136.42881.709.84649.36889.24738.41307.93522.0011.629511.098510.567610.03669.50542.5015.189014.451613.715012.977612.24063.0018.416817.570916.724315.877615.03673.5022.700821.571320.442719.313118.22664.0027.164025.747024.330322.912921.49544.5030.385228.916327.447525.978424.50965.0035.424333.629331.834230.038428.24336.0043.895441.747539.598837.450835.30207.0056.720153.699150.678047.656144.63528.0065.471362.180058.888355.596852.30619.0084.545779.826175.106170.386365.666510.0108.6250102.028995.434688.841282.248612.5158.3464148.7516139.1578129.5629119.978115.0206.4175194.4276182.4477170.4577158.476617.5250.3934236.6910222.8603209.1592195.456820.0327.8165309.9521291.2953273.4409255.578621.5384.6647363.2975341.9027320.5455299.1880压力(Mpa)温度（℃）2502702903103300.100.41560.40010.38570.37240.36000.150.62460.60100.57950.55940.54040.200.83420.80270.77360.74650.72140.251.04451.00480.96820.93430.90270.301.25401.20771.16341.12241.08440.401.67801.61521.55541.50001.44900.502.10812.02551.94951.88021.81470.803.41103.27183.14533.02832.92151.104.74604.54454.36124.19434.04101.406.11475.84375.59455.37945.17771.707.52197.18306.86076.58156.33092.008.97448.53508.14477.80617.49552.5011.503610.879410.35009.88889.48063.0014.184213.337712.635911.997911.51433.5017.053015.924315.016314.256513.85014.0020.077818.660317.499716.552715.74904.5023.040721.571720.102818.933317.93085.0026.448324.653222.858021.422120.25086.0033.154131.006228.857426.709125.05027.0041.613338.592235.570432.54883
