What is the compressed air flow rate at 1.8 bar?
Flow rate: 0.3m ³/min. Flow rate=pipe cross-sectional area multiplied by flow rate=0.002827X pipe diameter ^ 2X flow rate (cubic meters per hour) ^ 2: square. Diameter unit: mm. Knowing the diameter and pressure actually cannot calculate the flow rate. But it can be assumed that the loss of flow resistance is negligible, that is, when megapure compressed air flows to the pipe mouth, all pressure energy is converted into kinetic energy, that is, (v × v) ρ/2=P, that is, P=0.5 ρ V2. ρ - density, V2- velocity square, P - static pressure, flow formula: L=AV, A is cross-sectional area. The calculation principle is as follows. When designing in engineering, you can directly refer to the compressed air pipeline calculation table. Compressed air plays a role in 12 aspects when in a stove state:
1. In the production of powdered spices, compressed air has a particularly important significance, as it must be dry, clean, and almost sterile. This is a special challenge for compressed air processing.

2. Calculation formula for compressed air flow rate
The calculation formula for compressed air flow rate is: L=Av, where L represents the flow rate, A represents the compressed air outlet area of the Huaixun crack pipeline, and v represents the average flow velocity of compressed air in the pipeline. Given a pipeline diameter of 16mm and a pressure of 0.9mpa, the compressed air flow rate can be calculated as follows: Calculate the inner diameter of the pipeline: assuming the inner diameter d is 12mm. Calculate the outlet area A of the pipeline: Using formula A=× d2, substitute d=0.012m into the formula to obtain A=× 0.0122. Calculate the average flow velocity v of compressed air: Using the Bernoulli equation principle, assuming that the flow resistance loss is not taken into account, all pressure energy is converted into kinetic energy, i.e. P=0.5 ρ V2. Given P=0.9mpa and ρ as the air density of approximately 1.19kg/m3, V2=2P/ρ can be calculated, and then V=sqrt can be determined. Substituting P=0Pa and ρ=1.19kg/m3 into the formula yields v=sqrt ≈ 38.89m/s. Lead calculation and closed flow rate L: Using the formula L=Av, substitute the previously obtained A and v into the formula to obtain L=× 0.0122 × 38.89 ≈ 0.0044 cubic meters/second. Convert the flow rate to cubic meters per hour, i.e. L=0.0044 × 3600 ≈ 15.
