A water tower is a familiar sight in many towns. The purpose of such a tower is to provide storage capacity and to provide suffi

cient pressure in the pipes that deliver the water to customers. The drawing shows a spherical reservoir that contains 7.02 x 105 kg of water when full. The reservoir is vented to the atmosphere at the top. For a full reservoir, find the gauge pressure that the water has at the faucet in (a) house A and (b) house B. Ignore the diameter of the delivery pipes.

Note: The drawing referred to in the question is attached below

Answer:

gauge pressure that the water has at the faucet in house A = 254878.4 Pa

gauge pressure that the water has at the faucet in house B = 186278.4 Pa

Explanation:

Mass of water, m = 7.02 * 10^5 kg

Calculate the volume of water in the reservoir:

V = m/\rho

Where \rho = density of water = 10³ kg/m^3

V = \frac{7.02 * 10^5}{10^3} \\V = 702 m^3

Since the reservoir is spherical in shape, the volume of a sphere is given by the equation:

V = \frac{4}{3} \pi r^{3} \\702 = \frac{4}{3} \pi * r^{3} \\r = 5.504 m

By observing the diagram shown, the height of the tower to house A:

h = 2r + 15 = 2(5.504) + 15 = 26.008 m

The gauge pressure in house A can be given by the formula:

P_A  = \rho gh\\P_A = 1000 * 9.8 *26.008\\P_A = 254878.4 Pa

By observing the diagram shown, the height of the tower to house B:

h = 2r + 15 - 7 = 2(5.504) + 15 - 7

h= 19.008 m

P_B  = \rho gh\\P_A = 1000 * 9.8 *19.008\\P_B = 186278.4 Pa

serious [3.7K]
<span>The specific heat (or the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius) of copper is about 0.386 J/g/degree Celsius. This means that if we supply 0.386 J of energy to 1 gram of copper, its temperature will increase by 1 degree Celsius.</span>

There are many interesting applications of our energy density model to the flow of blood in the human circulatory system. One in
qaws [65]

Answer:

Pressure increases due to enlargement

Explanation:

Energy density is just a fancy name for pressure

Pressure is same at the bottom of the cups (same level-Pascal's law)

thus, Air pressure 1 + h1d1g = Air pressure 2 + h2d1g

= Air pressure 3 + (h2-h1)d2g +h1d1g

from the first 2, we get that since h2>h1, AP2<AP1

from the next 2, we get that since d2<d1, AP3>AP2

from first and third, we get that AP1>AP3

thus, finally AP1>AP3>AP2

for fluids flowing in tubes (blood vessel in this case)

P+0.5dv^2 + gh is constant (also called the bernoulli equation

for the same blood vessel, the heights remain same i.e h1=h2

for same flow rate, inc in area decreases the speed at which the blood flows as vA must remain same

hence, P increases due to enlargement

Answer:

1. Just because it is small doesn't mean it needs to be excluded. If that were the case I would've been out of my friend group a while ago

2. Look at it it's fricking beautiful (see attachment)

3. It is just a great planet I don't think there needs to be any reason given I meannn you agree?

4. There's no other reason needed it's fricking gorgeous and amazing it needs no other reason. It needs a freaking
