how about this case?
with the fluid pushing the shaft to turn there is an energy = 0.5mv2 = E1.
the power of the fluid = \rho*g*h*Q = P1
with the rotating shaft energy = 0.5Iω2 = E2
with 2 differnt energy we can determine the efficiency.
efficiency = \frac{E2}{E1} = \frac{P2}{P1}...
yes that one i know.
is something similar to finding the power output of a turbine connected to a shaft onto a flywheel. the flywheel is spining in constant angular velocity by connecting it to a generator or a dynamo to producing a power output.
i need to find the power generated before...
how do i calculate the power produced by a rotating disc?
for example given that the constant angular velocity is 30rad/s, diameter of disc is 0.5m, mass is 15kg.
or do u need more data to calculate the power? if yes, what data do u need?
