In our country, using natural resources, it is desired to generate electricity by placing a turbine between two water sources. The tangential velocity to the impeller of this turbine is calculated by the formula u = kuLaTeX: \ sqrt {2gHo} 2gHo. Here; The tangential velocity coefficient can be taken as ku = 0.46 ± 0.02, the head which represents the net energy in the turbine as H0 = 650 ± 5% m and the gravitational acceleration as 9.81 m / s2. Find the tangential velocity and the percentage error at that velocity.
