Discussion Overview
The discussion revolves around converting volumetric flow rates of steam from m3/hr to mass flow rates in kg/hr for a steam system operating at a pressure of 14.5 barg and a temperature of 1150 deg C. Participants explore the availability of steam tables for these conditions and question the validity of the temperature measurement.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant expresses difficulty in finding steam table values for the specified high temperature and pressure, suggesting the temperature meter might be incorrect.
- Another participant questions whether the provided steam tables are suitable for the required conversion, indicating a lack of familiarity with steam engineering.
- Concerns are raised about the high temperature being unusual for the given pressure, with one participant suggesting that more typical conditions should be considered.
- A reference to a GE document is made, noting that it describes steam entry conditions at much higher pressures and lower temperatures than those in the original query.
- One participant suggests that if the pressure is indeed accurate, the situation may involve extreme superheat, necessitating the use of superheat tables instead of saturated steam tables.
- A link to a NIST table is provided, which covers steam properties over a wide temperature range and pressures, but the participant notes that the high temperature remains questionable.
- Discussion includes a mention of the critical point of water, indicating that achieving such high steam temperatures may not be practical.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the validity of the temperature and pressure conditions, with multiple competing views regarding the feasibility of the specified steam conditions and the appropriate tables to use.
Contextual Notes
There are limitations related to the assumptions about the accuracy of the pressure and temperature measurements, as well as the applicability of the referenced steam tables for the extreme conditions discussed.
