3.3 The impeller of a centrifugal oil pump with inle and oullat radil of 5 and 13cm,reppe tively. is roeating at 4800pm. Oil with specific gravily of 0.81 ertits the pump at a rate of 45 lps (iiters per second). The blade angle at the impeller culle is pure ratial and the constans blade height is 4cm. Draw the velocity diagrams at both the inlet and oulle at the design ondition. Detemine the ideal head rise and input power required. 3.4 An axial-flow gas turbune of 8in. mean radius with the blade profile shown is notang at 2400rmm. Draw the velocity diagrams at both the inlet and outlet at design coodicion. If the Inexs fow rate of air is 7.2 lo. 1 s. what is the ideal shaft power outpat in honsepower? 3.5 Air lexes the nozele of an axial-tion uubine stage at 30 with respect to the langental diretuion, as shown, at an axial flow velocity of 6 if ips. If the rower blade speed at the mean radius is a so 6000pts, find the rotor blades angles b and s if the reaction of the stage is to be 505. Drw the velocity dagrams as bolh the inlet and outle of the rotor
