1.In a propeller turbine, the relative inlet velocity is (a) is constant all along the radius (b) varies directly with the radius (c) varies inversely with the radius (d) none of the above 2. Consider the following statements: The usual assumptions in one dimensional analysis of flow in a propeller turbine include: 1. Flow velocity is constant all along the radius in both inlet and outlet side of the blades. 2. In frictionless, ideal flow, the relative velocity is constant all along the radius. 3. The swirl velocity varies inversely with the radius. 4. The peripheral velocity varies
