The measurement of dynamic coefficients in a water tunnel is considered generally, and it is shown that the forces depend only on relative velocity provided the flow in the water tunnel is steady. A method of measuring the coefficient N_r, relating cross force to yawing angular velocity utilizing an internal balance, is described. Experimental results are compared with theory, showing good agreement in the case of the coefficient N_r.
