Unformatted text preview: or turbine implied? Each case has common following data: outer radius 300 mm, inner radius 150 mm, flow rate 0.057 , density 1000 , and . (In these picture, V indicates the absolute velocity, indicates the velocity relative to the blade. sub “1” indicates inlet, sub “2” indicates outlet) 4. A closed-loop water tunnel is to be used to study water flow in a laboratory. It is constructed of 300mm diameter hydraulically smooth pipe. The loss coefficient at each of the four bends is 0.1 and assumes friction factor is 0.01. The total length of the loop is 14 m. The design velocity is V=3 m/s. It is proposed that an axial flow pump running at about 300 rpm be used. Verify that an axial-flow pump is the correct type to employ. 80 80 30 30 30° (a) (b) (c) 45° 45° 30° 30°...
