Water leaves the guide passages of an inward-flow turbine at a radius

1. Water leaves the guide passages of an inward-flow turbine at a radius of 1.2 m. Its velocity is then 20 m ·s−1 at an angle of 70◦ to the radius. It enters the runner at a radius of 900 mm. Neglecting friction and assuming that the flow is entirely twodimensional, calculate the drop in piezometric pressure between the guide passages and the entry to the runner.

2. A kite may be regarded as equivalent to a rectangular aerofoil of 900 mm chord and 1.8 m span. When it faces a horizontal wind of 13.5 m ·s−1 at 12◦ to the horizontal the tension in the guide rope is 102 N and the rope is at 7◦ to the vertical. Calculate the lift and drag coefficients, assuming an air density of 1.23 kg · m−3.
