When fluid in a pipe is accelerated linearly from rest, it begins as laminar flow and then undergoes transition to turbulence at a time ttr that depends on the pipe diame- ter d, fluid acceleration a, density ρ, and viscosity μ. arrange this into a dimensionless relation between ttr and d.

ttr = fcn( p, D, a, μ)

Arranged onto a relation between ttr and D:

ttr( pa^2/ μ)^1/3 = fcn[D(p^2a/ μ^2)^1/3]

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
