Inlet and outlet air volume of the centrifugal fan!
Thread Content
Centrifugal fans compress and pressurize gases, so shouldn’t the volume of air at the outlet be less than that at the inlet? Theoretically, that’s right, right?
Without considering pressure, such a statement is fine.
Isn’t the unit for air volume something like cubic feet per hour? It’s rarely measured based on actual volume; of course, according to the law of conservation of mass, the same amount enters as exits
Ordinary ventilators don’t provide much pressure increase.
It’s the law of conservation of mass, dear. It’s correct under specific operating conditions, but under standard conditions, the amounts are equal
For an ideal gas, it is the case like this, but the mass flow rate remains the same. Let’s consider it from another perspective: lol
If the diameters of the inlet and outlet pipes are the same, does the kinetic energy at the outlet decrease according to Bernoulli’s equation, or is Bernoulli’s equation not applicable in this case?
