Song (2018) provides the basic version of the energy equation in (3.32) z ++- P = H. 29 Part A List all the variables in this equation along with their basic dimensions in [MLT] or [FLT]. Part B According to the Buckingham II theorem, the energy equation can be expressed with some number of dimensionless II groups. How many II groups are needed to express equation (3.32)? Part C Part of the energy equation is the pressure head hp = Ply. Starting with the three variables hp, P, and y, use Rayleigh's method to determine the exponents on Pand y.
