Bernoulli's Principle: a Level Pipe Contains a Nonviscous, Incompressible Fluid

question 28

Multiple Choice

Bernoulli's principle: A level pipe contains a nonviscous, incompressible fluid with a density 1200 kg/m³ that is flowing steadily. At one position within the pipe, the pressure is 300 kPa and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 kPa. What is the speed of the flow at this second position?

• A) 567 m/s
• B) 16.2 m/s
• C) 32.9 m/s
• D) 23.8 m/s
• E) 186 m/s

Definitions:

Level of Significance

A statistical threshold used to determine if a result can be considered statistically significant, often denoted by alpha (α).

Statistical Risk

Statistical risk quantifies the likelihood of a negative event occurring. It is often used in the context of financial markets, health studies, and other areas requiring risk assessment based on numerical data.

Variability

The extent to which data points in a statistical distribution or dataset differ from each other and from their mean.

Confidence Level

A statistical measure that indicates the degree of certainty or trust in the results obtained from a sample as representative of a larger population.
