At mid-radius an axial turbine stage is designed for 50% reaction, zero outlet swirl, and an axial velocity component of 200 m/s (uniform through the stage). The absolute flow angle at outlet from the stator is 65° from the axial direction. a.At the design point, what is the work done by the fluid at mid-radius on the rotor (kJ/kg)? b.For no change from turbine design flow conditions, but with a 20% drop from design rotor rpm, estimate the work (kJ/kg) done by the rotor at mid-radius.

Figure 8.18 shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft/s. The dynamic viscosity of the fluid is 4.0 x 105 lbs/ft². The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.
