Assignment 1 – Dimensional Analysis

Vocabulary terms, variables, and submission requirements for the physics assignment on dimensional analysis.

$$\Delta p$$

The pressure loss measured in a pipe flow system.

$$L$$

The length of the pipe in the pressure loss expression.

$$d$$

The diameter of the pipe.

$$\rho$$

The liquid density within the flow expression.

$$v$$

The average flow velocity of a liquid or the velocity of a particle relative to time.

$$\lambda$$

The coefficient for which the dimensional equation must be determined in the formula $\Delta p = \lambda \frac{L}{d} \frac{v^2}{2} \rho$.

$$t$$

Time, the variable upon which the velocity of a particle depends in the equation $v = ab + bt + \frac{c}{d+t}$.

$$F$$

The drag force that opposes the motion of a sphere through a fluid.

$$r$$

The radius of the sphere moving through a fluid.

$$\eta$$

The dynamic viscosity coefficient of a fluid, which is proportional to the drag force.

$$\eta_{SI}$$

The SI unit for dynamic viscosity, expressed as $Ns\,m^{-2}$.
