Fluid flow -- Determining the power of a blower
Thread Content
The blower draws the air from the workshop into an air duct with a cross-sectional area of 200mm*300mm and a length of 155m (roughness e=0.1mm), and then discharges it into the atmosphere. The volumetric flow rate is 0.5 cubic meters per second, the atmospheric pressure is 750 mm of mercury, and the temperature is 15°C. Determine the power required of the blower, assuming its efficiency is 0.6. [This post was last edited by WSL01218 on 2009-3-24 at 12:17]
For pipeline calculations of viscous compressible gases, the integral of gZ1+u1^2/2+dp/ρ = gZ2+u2^2/2+hf
The formula upstairs is incorrect, right? . Treating air as an incompressible gas, the Bernoulli equation can be used to obtain it
