| Abstract: | The problem that density variation of steam flowing in the steam pipe was discussed.The hydraulic calculation formula applying to steam heating pipe was derived based on continuity equation and momentum equation,and comparing with the formula provided in the literature.Sevral examples demonstrated that its accuracy is better,the hydraulic calculation inaccuracy reduced 5.6% equally. |
