Which of the following is not a fluid's global parameters?

Correct! Wrong!

The external diameter is not a universal factor. One of the most important pipelining parameters is it. It aids in deciding the kind of pipe to use and the material to make it out of.

Which of the following statements accurately describes the Hagen-Poiseuille equation?

Correct! Wrong!

Since it is believed to be incompressible and Newtonian, fluid flow is laminar. Through the pipe's constant cross-section, the flow is laminar. As a result, the fluid in the pipe does not accelerate. Hagen-Poiseuille hence predicated laminar fluid flow.

Which of the following is used to assess liquid pressure only?

Correct! Wrong!

Piezometers are pressure gauges that are solely used to gauge the pressure of liquid.

Which of the following gives the frictional coefficient for circular pipes?

Correct! Wrong!

The diameter of circular pipes is shaped in a round fashion. The head loss for a laminar fluid flow is inversely related to the fluid velocity. As a result, the relationship between velocity and friction factor is inverse. Therefore, "64/Re" is the appropriate selection.

Which of the following statements about the human body is untrue?

Correct! Wrong!

Inside the body, water is not changed into anything. It serves only as a carrier and helps the body expel pollutants through perspiration and urine.

What statement regarding limiting reagents is accurate?

Correct! Wrong!

The reactant that completely reacts in a reaction is known as the limiting reagent.

Which of the following relates to customer judgments of food?

Correct! Wrong!

Sensory analysis examines how a consumer evaluates the dish.

Which aspect of the food sector includes industry lobbying, local and international laws, quality and food safety, etc.?

Correct! Wrong!

Food regulation safeguards industry lobbying, compliance with national and international laws, food quality, and food safety.

Which of the following DOES NOT account for 90% of any food's dry weight?

Correct! Wrong!

90% of the dry weight of every food is made up of proteins, lipids, and carbohydrates.

What mathematical method is employed to forecast physical parameters?

Correct! Wrong!

The process of dimensional analysis is employed to identify the physical factors that affect fluid flow. The analysis is founded on the fundamental units. The fundamental units are mass, length, and time.

Which of the following is not a gadget that measures pressure?

Correct! Wrong!

Current is measured with a galvanometer.

Which of the following is being affected by the same forces?

Correct! Wrong!

Similar forces are at work in dynamical analogies. This indicates that the ratios of all the forces acting on the fluid particles are constant. The ratio of the forces acting on the boundary surfaces is also constant.

Which of the following is an example of water boiling in a container?

Correct! Wrong!

It is neither a batch process nor a semi-batch process because nothing is going into the container but steam, which is also leaving the container.

Which of the following qualifies as a state function?

Correct! Wrong!

Entropy is a state function since it is independent of the process's trajectory.

Which of the following is a primary component of an organic compound?

Correct! Wrong!

An organic compound is any substance that has carbon, hydrogen, and oxygen as its main components.

Which of the aforementioned makes up the lion's share of natural gas?

Correct! Wrong!

About 75% of natural gas is made up of methane.
