A system has basic dimensions as density \( [D] \),
\( \mathrm{P} \)
velocity \( [V] \) and area \( [A] \). The dimensional
W
representation of torque in this system is:
(1) \( \left[A V^{2} D\right] \)
(2) \( \left[A^{2} V D\right] \)
(3) \( \left[A^{3 / 2} V^{2} D\right] \)
(4) \( \left[A V^{\beta / 2} D\right] \)
