The steam velocity in a steam distribution system should be within certain limits to avoid excessive wear and tear.
energy content of flash steam at atmospheric pressure. Example. Consider a vent pipe with the following conditions: Velocity of flash steam: 300 feet per minute.
Tutorial to the basic physics behind flash steam generation.
Flash steam velocity - mahjong
The energy - or enthalpy - made available when pressure is reduced, will evaporate a part of the water, producing flash steam. Phase changes, mass and energy balances, mixed-phase flows, non-Newtonian compressible gases, changes in pressure and velocity, and production-based or seasonal load swings are characteristics of this complex system. This condensate is usually discharged from the steam lines at system operating pressure by a properly sized and selected steam trap. When the heating load falls and the pressure in the system begins to increase, the pressure reducing valve supplying the make-up steam closes down. Fluid Flow and Pressure Drop. Provide good quality steam at the required demand and pressure of the user. A portion of the pipe will be occupied by flash steam and the balance with condensate.
