Issues with the blower’s power?
Thread Content
The centrifugal blower uses air at atmospheric pressure; it has a radial design. Its design temperature is 100 degrees, and the design pressure is 10 kPa gauge. I understand this to mean an inlet pressure of 101 kPa. The flow rate is 91,000 kg/h. How can I calculate the power required for this blower? According to the formula N=PQ/102η(KW), where P is the wind pressure in mm of water column, Q is the flow rate in m3/s, and η is the efficiency. First, it is necessary to determine whether this formula is correct; if it is, then how should the wind pressure value be determined – should it be the design pressure? Based on everyone’s experience, what would be the approximate power of this blower? Could someone with expertise please explain? Thank you! !
The flow rate is as high as 91,000 kg/h (first convert this flow rate to m3/s); I estimate that it requires at least 1200 KW
Please, the original poster, check again what you have posted! Because the unit of flow rate is cubic meters per hour, not in kilograms; haha, was it written incorrectly?
