Acentrifugal pump rotates at n˙ = 740 rpm. suppose the pump has some swirl at the inlet (α1 = 10°) and exits at an angle of 35° from radial (α2 = 35°). the inlet radius is r1 = 12.0 cm, at which the blade width b1 = 18.0 cm. the outlet radius is r2 = 24.0 cm, at which the blade width b2 = 16.2 cm. the volume flow rate is 0.573 m3/s. assuming 100 percent efficiency, calculate the net head produced by this pump in "m" of water column height. also calculate the required brake horsepower in w. the density of water is taken as rho = 998.0 kg/m3.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
