At that depth, the weight of the water above, pushing downwards, is about 150 times normal atmospheric pressure ( Source: University of Illinois at Urbana-Champaign Ask the Van ). C. View Answer. Our second recommended source is in academia at UCSC - Physics dept. I cubic foot of water will expand to 16 cubic feet of steam.. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser.The greatest variation in the design of steam-electric power plants is due to the different fuel sources. However, its very primary information. To a reasonable approximation steam at 100C can be treated as an ideal gas. We discuss the role of pressure/temperature relief valves in protecting against these hazards, at RELIEF VALVE, TP VALVE, BOILER and at RELIEF VALVE, WATER HEATER. This means that under ideal conditions, 1 part of liquid water expands to 1700 times the volume as steam when boiled. How does a Steam Turbine Work? This cookie is set by GDPR Cookie Consent plugin. where we list various causes of T/P relief valve leaks.When you're confident the problem isn't the valve itself you look at the starting water pressure, the temperatures involved, and external causes like water hammer or hot water expansion. For membership enquiries: membership@cibse.orgThis CIBSE document, Appendix 1.A1 Hydronic system design, [PDF] The density of any object or material is its mass per unit of volume. But when its heated, its intermolecular space increases. Here we provide a more theoretical discussion of how we might calculate the pressures that can be expected to occur in a water tank due to thermal expansion. The expansion ratio of steam at 100o C (212o F) is 1700:1, but as the volume of water used to cool the upper layer is small, the expanded volume is still relatively small (in comparison to the contraction of the upper layer). The water supplied to the boiler that is converted into steam is called feed . Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. It does not store any personal data. - this is probably not quite correct as the expansion rate for heated water is not linear. When water is heated it expands rapidly adding about 9 % by volume.
