Describe a method of calculating the flow rate in the normal pump versus the pump with the narrowed vessels you described above.

charle [14.2K]

Answer:

Taking into account that:

The flow velocity u of a fluid is a vector field

u = u (x, t)

What gives the velocity of a Fluid Plot at position x y time t.

q = || u ||

Now if the flow is continuous as it happens in the blood vessels then:

The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.

Explanation:

As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.

So this is where we have to put emphasis on the biophysics branch that explains the following:

The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.

Indeed, according to Bernoulli's principle:

P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2

<em>Your question is incomplete. Please read below to find the complete question.</em>

A) Wear protective barriers such as gloves, regardless of your relationship with the person you are helping.

A protective barrier is a bodily layer on the pinnacle of a corrosion-prone metal surface and is meant to prevent corrosion. Protecting barriers are introduced to metallic surfaces by way of painting the floor with a non-metal coat or plating with steel.

Protection boundaries within the place of work can be beneficial within the mission to reduce the likelihood of a place of job twist of fate. they may be structures that are designed to save you access right into a potentially dangerous area, or regions that are a potential risk. First and foremost, they may be used to mitigate dangers.

With secure regions, bodily boundaries can be vital in ensuring there's no safety breach in positive limits. However, shielding obstacles are added to the bodily layer to outline the physical limits in a particular setup. It additionally protects the sports or precise regions.

You are attempting to control bleeding on a coworker who has cut himself while using a hand tool on a job site. How should you best address the possibility of being exposed to an infectious bloodborne disease?

A) Wear protective barriers such as gloves, regardless of your relationship with the person you are helping.

B) Avoid touching the person's blood with your bare hands to minimize your chance of exposure

C) Wash your hands with soap and water before and after care

D) Only use PPE if required by your employer's occupational exposure control plan

How to calculate the heart rate from the electrocardiogram ?

Masja [62]

Answer:

ECG paper is a grid where time is measured along the horizontal axis.

Each small square is 1 mm in length and represents 0.04 seconds.

Each larger square is 5 mm in length and represents 0.2 seconds.

Voltage is measured along the vertical axis.

10 mm is equal to 1mV in voltage.

The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form

Heart rate can be easily calculated from the ECG strip:

When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.

For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).

The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.

For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).

How would it affect the care the people receive if nurses made generalizations about groups of people?

Yuliya22 [10]

Answer:

They would be biased towards the patient and the patient wouldn't get the best care or get to much attention and the nurse would be too distracted for others.
