What is BS 5860 - Hydraulic turbines, storage pumps and pump-turbines about?
The thermodynamic method results from the application of the principle of conservation of energy (first law of thermodynamics) to a transfer of energy between water and the machine through which it is flowing. BS 5860 is a British Standard that serves as a basis for the measurements to be made on hydraulic turbines, storage pumps, and pump turbines and for the computation of their efficiency by applying the thermodynamic method. This method is based on the evaluation of the energy per unit mass of water delivered to a turbine shaft or received by water from a pump shaft. BS 5860 may be determined by measurements of the performance variables (Pressure, temperature, velocity, and level) and from the thermodynamic properties of water.
