When the value of the output cannot be determined even if the value of the controllable input is known, the model is:_________

Nuetrik [128]

Answer:

<em>c. stochastic.</em>

<em></em>

Explanation:

A stochastic model is a tool in statistics, used to estimate the probability distributions of intended outcomes by the allowance of random variation in any number of the inputs over time. For a stochastic model, Inputs to a quantitative model are uncertain, and the value of the output from a stochastic model cannot be easily determined, even if the value of the input that can be determined is known. The distributions of the resulting outcomes of a stochastic model is usually due to the large number of simulations involved, and it is widely used as a statistical tool in the life sciences.

Water is flowing in a metal pipe. The pipe OD (outside diameter) is 61 cm. The pipe length is 120 m. The pipe wall thickness is

Yuki888 [10]

Answer:

1113kN

Explanation:

The ouside diameter OD of the pipe is 61cm and the thickness T is 0.9cm, so the inside diameter ID will be:

Inside Diameter = Outside Diameter - Thickness

Inside Diameter = 61cm - 0.9cm = 60.1cm

Converting this diameter to meters, we have:

$60.1cm*\frac{1m}{100cm}=0.601m$

This inside diameter is useful to calculate the volume V of water inside the pipe, that is the volume of a cylinder:

$V_{water}=\pi r^{2}h$

$V_{water}=\pi (\frac{0.601m}{2})^{2}*120m$

$V_{water}=113.28m^{3}$

The problem gives you the water density d as 1.0kg/L, but we need to convert it to proper units, so:

$d_{water}=1.0\frac{Kg}{L}*\frac{1L}{1000cm^{3}}*(\frac{100cm}{1m})^{3}$

$d_{water}=1000\frac{Kg}{m^{3}}$

Now, water density is given by the equation $d=\frac{m}{V}$ , where m is the water mass and V is the water volume. Solving the equation for water mass and replacing the values we have:

$m_{water}=d_{water}.V_{water}$

$m_{water}=1000\frac{Kg}{mx^{3}}*113.28m^{3}$

$m_{water}=113280Kg$

With the water mass we can find the weight of water:

$w_{water}=m_{water} *g$

$w_{water}=113280kg*9.8\frac{m}{s^{2}}$

$w_{water}=1110144N$

Finally we find the total weight add up the weight of the water and the weight of the pipe,so:

$w_{total}=w_{water}+w_{pipe}$

$w_{total}=1110144N+2500N$

$w_{total}=1112644N$

Converting this total weight to kN, we have:

$1112644N*\frac{0.001kN}{1N}=1113kN$

According to your equation, what is the functional relationship between the height of the water h_1 and the speed of the flow v_

larisa [96]

This question is incomplete, the complete question is;

Starting with the full Bernoulli’s equation, simplify the equation for the case diagrammed below, where Point 1 is at the top of the water at height h1, with negligible flow speed v1=0, and Point 2 is at height h2=0. Both Point 1 and Point 2 are open to the atmosphere so P1 = P2 = Patm.

According to your equation, what is the functional relationship between the height of the water h1 and the speed of the flow v2 at Point 2?

Answer:

the functional relationship between the height of the water h1 and the speed of the flow v2 at Point 2 is v2 = √2gh1

Explanation:

Gravitational acceleration = g

Density of water = P

Pressure of the water at point 1 = p1 = patm

Speed of the water at point 1 = v1 = 0 m/s

Height of point 1 = h1

Pressure of the water at point 2 = p2 = patm

Speed of the water at point 2 = v2

Height of point 2 = h2 = 0 m

Now, Using Bernoulli's equation at point 1 and 2,

p1 + Pv1²/2 + Pgh1 = p2 + Pv2²/2 + Pgh2

patm + P(0)²/2 + Pgh1 = patm + Pv2²/2 + Pg(0)

Pgh1 = Pv2²/2

gh1 = v2²/2

v2² = 2gh1

v2 = √2gh1

Therefore the functional relationship between the height of the water h1 and the speed of the flow v2 at Point 2 is v2 = √2gh1
