A single-stage axial flow pump with outer radius r2 =0.240 m and inner radius r1 =0.120 m is given. At a radius of r =0.090 m, absolute flow flows in from the axial direction just before the impeller inlet and relative flow flows out in the axial direction just after the impeller outlet. Assuming a flow rate Q = 0.265 m^3/s, a water density ρ = 1.000 × 103 kg/m^3, a rotation speed n = 2.4 × 10^3 rpm, and a gravitational acceleration g = 9.81 m/s^2 , and assuming that the theoretical head Hth = W/g (W: specific work) derived from Euler's law is constant at all impeller radii, answer the following questions.

This is from Chapter 10 of Sustainable Energy second edition by Richard Dunlap Two locations have the same average wind velocity. Location A has a constant wind velocity of 10 m/s, while Location B has a wind velocity of 5 m/s for 12 hours per day and a wind velocity of 15 m/s for 12 hours per day. Compare the total energy produced per day for identical wind turbines at the two locations. The energy is given by the formula E = 0.5*(air density)*(efficiency)*velocity^3*(Turbine area)*time. Keep the answer in terms of (efficiency)*(Area). **Also is v average velocity or regular, non-average velocity?***
