Help in designing water turbine for given wattage

    Hey there :)

    Have to design a water turbine to generate electricity to power an 80 watt pump.

    We're looking at a turbine that generates 110 watts.

    We're allowed to make up, so to say, our flow rate, and potential head.

    We've used engineering toolbox to decide what flowrate and then try to use

    q = v*a to get an area of our screw turbine.

    acceleration to due gravity is 9.82 m^2/s, so how do we get the velocity of water flowing down at an angle of 63 degrees (has to be 63 as the helix angle of the screw is 63 and needs to be at a horizontal)

    Any tips?

    Are we right in the way we're going about this?

    This is the calculator used to get the values needed to satisfy 110 watts putting in the efficiency of the turbine for the efficiency of the pump here.

    calculator

    Thanks in advance :)
