Mutual exclusive axis systems 's ' and 'r' representing airflow in aerospace with viscosity and velocity of air speed both functions of 's' and 'r' with viscosity a function of 'r' equal too another function of viscosity a function of s, with change of product velocity of air speed times viscosity both around change of 'r and 's' equal too change of product of velocity times viscosity around a change of 's'.
