Which is a dimensionless parameter? A. Froude Number C. Viscosity B. Angular Velocity D. Density

1. To determine the dynamic viscosity of a liquid you take repeated measurements of the liquid density and kinematic viscosity. These data are summarized in the following table: Avg. measurement Total Uncertainty P 999 kg/m³ ±0.5% V 1.23 mm²/s ±0.01 mm²/s kg Ns What is the dynamic viscosity? Give dynamic viscosity in units of; which is the same as ms 2. Determine the absolute and relative uncertainties in the dynamic viscosity.

FLUID MECHANICS FIND PRESSURES IN A, B, C, AND D

Question 2: The pressure drop, AP, in a horizontal pipe depends on the pipe diameter, d, pipe length, L, pipe roughness, ɛ, average velocity, V, density of the fluid, p, and absolute viscosity of the fluid, u. Express the variables in non-dimensional form using Buckhingham-Pi theorem
