Seeking help with calculating compressed air consumption

Thread Content

Given: 1. Without compressed air in use, the stable pressure in the storage tank is 0.5 Mpa, with an air compressor at the front end continuously supplying air； 2. Open the pressure relief valve; it is known that there are 30 small holes with a diameter of 5 mm at the spray outlet ； Calculation: 1. For a continuous jet process, what is the consumption of compressed air per minute? 2. During the continuous jet process, what is the compressed air flow velocity at each nozzle? 3. During the continuous jet process, what is the pressure in the storage tank? 4. For the continuous jet process, what is the formula for the diffusion angle at each nozzle? Can the above conditions be used to calculate the aforementioned issue? I’m seeking help from experts; it would be great if there are formulas available for learning, or if I can find textbooks and materials that can help with learning
