1... For blowing pipes with a diameter of DN100 and a length of 100 meters, how to calculate the steam flow rate? According to the "Code for Construction and Acceptance of Industrial Metal Pipeline Engineering" (GB 50235-97), steam pipelines should be purged with high flow steam at a flow rate of not less than 30m/s. If blown at a speed of 40m/s, the pressure inside the 100 meter long pipeline, considering the resistance of bends and fittings, is about 0.3MPa. Based on this calculation, the required flow rate is 40 × 0.1 × 0.1 × 0.785, approximately 0.314 cubic meters per second. Under such conditions, the bulk density of steam is approximately 0.0010829 (m3/kg), therefore, the flow rate can be converted into a weight flow rate. Calculated, the weight flow rate of steam is 290 kilograms per second. It is very important to ensure that the flow rate is sufficient and the number of components is high when blowing steam pipelines, which can effectively remove impurities and sediments inside the pipelines. Usually, in order to achieve optimal results, the flow velocity should be higher than 30m/s, or even reach 40m/s or higher. In practical operation, it is also necessary to consider the resistance loss of the pipeline and other factors to ensure the effectiveness and safety of the blowing process. For a DN100 pipeline, if the blowing flow rate is set to 40m/s, the calculation of steam flow through the pipeline at a pressure of 0.3MPa can be simplified to the above formula. By adjusting the flow rate and pressure, the blowing effect can be further optimized to ensure cleanliness inside the pipeline. When blowing the steam pipeline at the head of the mountain, it is also necessary to pay attention to some details. For example, ensuring that the steam temperature remains around 230 degrees during the blowing process helps to better remove deposits and impurities. In addition, depending on the actual situation, it may be necessary to increase the blowing time or change the blowing strategy to ensure that the pipeline cleanliness meets the requirements. In summary, accurate calculation of steam flow rate and velocity can effectively carry out steam pipeline purging work, ensuring the cleanliness and safe operation of the pipeline. This not only helps improve production efficiency, but also extends the service life of pipelines and reduces maintenance costs.

3. How to calculate the flow rate of saturated steam?

Regarding the relationship between flow rate, pressure, pipe diameter, and flow velocity, in general engineering calculations, for water pipelines, the pressure is usually 0.1-0.6 MPa, and the flow velocity of water in the pipeline is 1-3 meters/second, often taken as 1.5 meters/second.. Flow rate=pipe cross-sectional area X flow rate=0.002827X pipe diameter ^ 2X flow rate (cubic meters per hour) ^ 2: square. Pipe diameter unit: mm Pipe diameter=sqrt (353.68X flow beam hunger/flow rate) sqrt: The formula for square root saturated steam is the same as that for water, except that the flow rate is generally taken as 20-40 meters per second. If accurate calculation is required, the flow velocity should be assumed first, and then the Reynolds number should be calculated based on the viscosity of water, the density of rubber shirts, and the pipe diameter. The resistance coefficient along the pipeline should be calculated based on the Reynolds number, and the equivalent p
