I was thinking of building a horizontal-axis wind turbine and testing various blade designs but i can't afford a generator to test the power output of each variation.
Is it sensible/possible to get the output without a generator? Can equations in finding torque be used?
Good day! I would just like to ask on how to convert a particular piece wise function to a heaviside equation.
For a function,
f(t) = t2 if t < 2
t - 1 if t >= 2
the heaviside equation would be,
H(t) = t + (t-1 -t)u2(t)
H(t) = t - u2(t)
but i can't comprehend on...
