I would like to ask experts how to design hydraulic turbines
Thread Content
I would like to recover the energy from water, with the following key parameters: 1. The pressure of the water used for power generation is 3.8 MPa, and its temperature is 80°C; the pressure after passing through the hydraulic turbine is required to be 0.6 MPa. 2. The hydraulic turbine does work on the pump; the parameters of the pump are that the inlet water is at atmospheric pressure, while the outlet is designed to be at 1.0 MPa. Problems existing: 1. How to calculate the power of a hydraulic turbine, and what is the typical efficiency of hydraulic turbines? 2. To meet the requirements mentioned above, what should be the pumping volume of the pump? I hope those who are knowledgeable can offer some guidance; it would be sufficient if you could tell me the calculation method. I am extremely grateful!
The flow rate of the power water is 60 tons per hour
