Estimate the power available in a tidal stream flowing at 3m/s using a 5m diameter propeller turbine.
Hello and thank you for posting your question to Brainmass.
The power P generated by an ideal turbine (no losses) is given by:
P = (r * A * v^3)/2
r is the water density (1025 kg/m^3 for sea water)
A is the sweep area of ...
The power is a propeller turbine in a tidal stream is determined.
