A jet of freshwater strikes a series of vanes of a turbine at 25° with the direction of motion and leaves it at 150° absolute with the direction of motion. The absolute inlet velocity of the jet is 25 m/s and the vanes move at a velocity of 10 m/s. Ignore friction across the vanes. Calculate: 1.1 the vane inlet angle. 1.2 the vane outlet angle. 1.3 the power/kg of water and, 1.4 the hydraulic efficiency.

Connections

In steel structures, connections are the members that join two or more steel members. The connections are the most important members of any steel structure, and hence, they are designed more carefully. The majority of the construction cost of steel structures is incurred due to the connections. The design of connections is done as per the recommendations and specifications of the American Institute of Steel Construction (AISC).
