Blade peripheral speed at mean radius for Impeller I,

`U_(I)`

. Volumetric Flow Rate,

`Q=25(m^(3))/(m)in`

; Working Fluid: Water at STP Impeller #I:

`\omega _(I)=3,000rpm;,`

Impeller #II:

`\omega _(II)=-3,000rpm`

Degree of Reaction: Impeller # I -

`R=0.50`

; Impeller # II:

`R=`

unknown Blade Tip Radius:

`95mm;`

Blade Hub Radius:

`37.5mm`

Assume flow is axial at BOTH Section 1 and at Section 4. Assume blade angles equal corresponding flow angles. Perform your calculations at the mean radius as defined in Peng (Pg. 45). SECTION # 1 At Section #1, determine: Absolute Velocity,

`V_(1)`

, and Relative Velocity,

`W_(1)`

. Draw the Vector diagram of velocity vectors at Section #1, to scale. Determine the blade angle,

`\beta _(b1)`

on Impeller I.
