QUESTION 2 (PLO1, CLO2, C5)
Ali, a process technician in the chemical industry is pondering how to write an equation for a mixing process in a large tank. He knows that the shaft power W supplied to the stirrer blades is a function of stirrer diameter D, liquid density $\rho$, liquid viscosity $\mu$ and the angular velocity $\omega$ of the spinning blades but he doesn't know the functional relationship. As a process engineer, help Ali to generate a dimensionless relationship between these parameters by using the method of repeating variables. Take $\omega$, $\rho$, and D as the repeating variable. [DIMENSION OF $\omega = T^{-1}$]
