What is cardiovascular eficiencia

Physics
1 answer:
Minchanka [31]4 years ago
5 0
English: Cardiovascular efficiency depends on a number of factors. One measure is called stroke volume, which is the volume of blood pumped per heartbeat. A fit individual has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat.

Spanish: La eficacia cardiovascular depende de una serie de factores. Una medida se denomina volumen sistólico, que es el volumen de sangre bombeada por latidos cardíacos. Un individuo en forma tiene un volumen de movimiento mayor, lo que significa que un mayor volumen de oxígeno es entregado al cuerpo por latidos cardíacos.

It looks like Doppler effect. Sound waves passing through a big way until they get to your ears. We got the highest frequency when we receive it, while it goes it remains the same and when it goes down we receive lower frequency.

A thin stream of water flows smoothly from a faucet and falls straight down. At one point the water is flowing at a speed of v1
MrRa [10]

Answer:

The vertical distance between these two points is 12.28 cm.

Explanation:

Given that,

Speed of water = 1.23 m/s

Diameter at lower point d'= 0.787 d

We need to calculate the speed of water

Using continuity equation

A_{1}v_{1}=A_{2}v_{2}

\dfrac{\pi\times d^2}{4}v_{1}=\dfrac{\pi\times d'^2}{4}v_{2}

v_{2}=v_{1}\times(\dfrac{d}{d'})^2

Put the value into the formula

v_{2}=1.23\times(\dfrac{d}{0.787d})^2

v_{2}=1.98\ m/s

We need to calculate the  vertical distance h between these two points

Using Bernoulli theorem

P_{1}+\dfrac{1}{2}\rho v_{1}^2+\rho gh_{1}=P_{2}+\dfrac{1}{2}\rho v_{2}^2+\rho gh_{2}

Here, P₁ = P₂ = atmosphere pressure is same because both end is open

\dfrac{1}{2}\rho(v_{2}^2-v_{1}^2)=\rho\times g(h_{1}-h_{2})

(v_{2}^2-v_{1}^2)=2g(h_{1}-h_{2})

2g\times\Delta h=(v_{2}^2-v_{1}^2)

\Delta h=\dfrac{1.98^2-1.23^2}{2\times9.8}

\Delta h=12.28\ cm

Hence, The vertical distance between these two points is 12.28 cm.
