The main pipe has a diameter of DN50, and it is equipped with 15 nozzles; each nozzle has a diameter of 6 mm. What is the volume of compressed air required when the injection pressure is 3 kg? How large a compressor is needed? What size would a gas tank with an 8kg pressure need to be?
No time was given, or it was a continuous state of work
It is a continuous state; the gas tank serves as a backup and for balancing purposes. It is necessary to consider the compressor’s capacity in terms of the required gas flow rate, as well as the potential duration for which the gas needs to be supplied
Well, this is a continuous operation that needs to be carried out over a long period of time. I have no idea how to proceed at the moment; could you give me an algorithm? I’m not trained in this; I only have some basic knowledge
For this, you can refer to the book 【Process Piping】; specific design details are available under certain conditions
When the pressure at the nozzle exit is below 1.1 kg, 15 Ø6 nozzles achieve a flow rate of 1425 kg/h for 3 kg of compressed air at 20 degrees Celsius. If it is higher than 1.1 kg, it is related to pressure; the specific flow rate can only be determined once the outlet pressure is known.
