    THICKNESS OF ROTATING WHEEL

    Dear All I am designing a water turbine but I am not sure to calculate the thickness of the end plate holding the blade rows. This end plate act as a loaded rotating wheel, transmitting 300 KW at 820 Rpm. as attached. Could anyone give the applicable formula?? Thank you

    burst rpm

    Hi ishvaaag. Bursting disk is due to centrifugal force due to rotation. The force will tear away the rotating material if it exceeds the force that "hold" the material in place. This force depends on the peripherial speed and the density, whatever the thickness is. The equation I usually use...

    Mini Hydro Scheme

    Halllo jasonf987 I am new in the group but the following information might be useful The Head is 60 m and the flow .578 m3/sec. A well designed plant should produce 220 Kw. The pump: Pumps speed is limitted to the allowable stress of the impeller. For good grade steel impeller the maximum...

    Mechanical Calculation on support

    Daer All I am now for the first time designing a 300 KW hydro cross flow turbine. The runner diamater is 463 mm, rotating at 667 RPM, excerting 4300 NM torque. All power is transmitted to one end plate as there is no through shaft. The hub diamater would be 200 mm, and the shaft is 90 mm...
