The Reynolds number is an engineering parameter that relates to the volume flow rate of a fluid through a tube of diameter d as Red = 4Q/nd where v is the fluid kinematic viscosity. Determine the Reynolds number and its uncertainty by general analysis given d=50.4±0.1 mm, Q=0.213± 0.005 m-Ys, v=0.999 x10-6-0.005 x10-6m2/s, which vari- able contributes the most to the overall uncertainty? Assume uncertainties are at 95% confidence.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

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.
