WebThe resulting volume of flash steam from the 18.6 kg of boiler water is: (18.6 kg x 16%) x 1.673 m3/kg = 4.98 m3. For comparison, the volume of water, is reduced to: (18.6 kg x 84%) x 0.001 m3/kg = 0.015 6 m3. The very high energy flowrate, and huge change in volume between the upstream and downstream sides of the blowdown valve, mean that ... Webpressure in a piping system with vapor flow. The acoustic pressure is usually created from pressure-reducing devices due to high pressure drops and mass flows of vapor services. These acoustic energies excite the pipe wall circumferentially due to high-frequency sound waves in the range of 500–2,500 Hz, where most of the energy is captured.
