- Mention the advantages of Vertical Axis wind turbine.Pls. answer thank you! A running at 400 rpm has a specific speed of 60 rpm and head available is 41 m. If the rating of each turbine installed is 100 kw, how many turbines must be used?Name and briefly describe the differences between the two basic types of dynamic turbine.
- Explain two types of turbine which depend on the action of water on the moving blades.Q14: Arancis turbine operates under a head of (24.5m) and consumes (10.5m³/s) of water whilst runnlag at (225 r.p.m). The velocity of flow at inlet (6.5 m/s), the inlet blade angle is (65), assume hydraulic efficiency is (90%) and no volume and mechanical losses and velocity of whirl at exit equal to zero. Calculate i) Diameter of the runner at entry, ii) Specific speed of turbine runner. Q=TD.B.VP)2. Calculate the maximum efficiency of Pelton turbine using velocity diagram.
