1. Air passes through a 1m-diameter ventilation duct at a velocity of 3.0 m/s. Calculate the volumetric flow rate and the mass flow rate assuming that the air has a density of 1.2 kg/m3.
2. During a ventilation survey the cross-sectional area of a mine airway is measured to be 14.5 m2. Anemometer traverses of the airway have been undertaken and the results from four such traverses at the area measuring site indicated that on the first pass a total of 231 m of air was registered on the anemometer. In the second traverse 245 m was measured, in the third 238m and in the final traverse 228m. Given that each anemometer traverse was timed over 100 s, determine the average flow velocity of the air and the air quantity flowing.
Calculate the present equivalent value of the machine and the contribution to the cost of processing the material, per kg, resulting from the capital cost of the machine.
