  • Flow measurement - Wikipedia

    2 days ago · The turbine wheel is set in the path of a fluid stream. The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion. When a steady rotation speed has been reached, the speed is proportional to fluid velocity. Turbine flowmeters are used for the measurement of natural gas and liquid flow.

  • Small wind turbine - Wikipedia

    2 days ago · Design Blades. Smaller scale turbine blades are usually 1.5 to 3.5 metres (4 ft 11 in–11 ft 6 in) in diameter and produce 0.5-10 kW of electricity at their optimal wind speed. The majority of small wind turbines are traditional horizontal-axis wind turbines. In some situations, vertical axis wind turbines have operational advantages in maintenance and placement due to their simplicity ...
