Chapter 9, Problem 7ICA

When a simple turbine is used for mixing, the following variables are involved:

P = Power requirement [=]watt [W]
N = Shaft speed [=] hertz [Hz = 1 s ]
D = Blade diameter [=] meters [m]
W = Blade width [=]meters [m]
ρ = Liquid density [=] kilograms per meter cubed [kg/m3]

1. While researching fluid dynamics, you come across a reference to the dimensionless number called the Laplace number, given by the equation below. SpL La = where: kg p= fluid density [=]: m3 H= fluid viscosity [=]- m-S L = length [=] ft What are the dimensions for delta, &?
I need help with the below table
physical quantities m, r, u, a, and t with dimensions [m] = M, [r]= L, [v] = LT, [a] = LT-2, and [t] = T. Enter the dimensional expression of the quantity on the right-hand side of each equation. Your answers may contain only M, L, T, and exponents. Assume that each of the following equations is dimensionally consistent. F = ma [F] =
