Question
In a certain hydraulic turbomachine, the following data apply:
Inlet blade velocity is 20 m/s. Vu1=21 m/s; Vr1=10 m/s.
At the exit, V2 is purely axial and has a value of 14 m/s, and blade speed is
9 m/s. Is this power absorbing or power producing? Find E and the changes in
static and stagnation pressures. Would this machine be classified as a purely
radial, purely axial, or mixed flow type?
Ans: E=420 J/kg; Δpstag=420 kPa; Δpstat=247.4 kPa
