12:44 Search 4G Expert Q&A Done I have designed and built a small-scale wind tunnel, I know that the average velocity at the fan outlet (tunnel inlet) is 22.45m/s, and the volumetric flow rate is 450m^3/h. At the end of the tunnel the velocity is 10.55m/s and the vloumetric flow rate is 380m^3/h. The power of the fan is specified as 140W. Is there a way to calculate the pressure energy losses in the system, and also the power given to the flow by the fan so that the efficiency can be calculated.
