1. Ok I have to build a real life wave-maker for my Final Year Project(FYP). My wave-maker design is as shown below:

The proffessor said I need to be able to calculate the torque of the motor before I order it. I start out by calculating the force needed to move the water using the flap paddle.The equation I have applied is:
Water's Volume = length*breadth*height = (1.23)*(0.57)*(0.45) = 0.3155 meter^3
The torque is
t = r*f*sin(theta)
r = 0.35m
theta = 10 degree
f = ??
I know Force = m*a
m = water's volume in this case = 0.3155 meter^3
but what is the acceleration, "a" here though??
The spring is there to keep the flap paddle in neutral positon when the water is quiet.
So my question is: How would I determine the minimum force that I need to drive the paddle? And how would I go from there to determine the torque that my motor would need to move the paddle??
Sorry if this seems a bit messy, first time poster
