Answer:

I select false because engineers are not the only thing we have, we have scientists doctors mathematicians and much more to give safety standards

Answer:

False.

Explanation:

Even though engineers are designing their buildings and products to meet safety expectations, things can go wrong, and engineers should never be allowed to have final say. That is the main reason why we have safety inspectors, and are able to live our lives safer today. If there were no second checks on different things, if one were to fail, we would know it for certain to be the engineer, and he does not want to take the blame, (and possibly a lawsuit), that may appear after the accident. If we want maximum safety, we ensure that there are many more people who prepare and examine products closely from time to time.

Draw the Pressure - Temperature Diagram showing the liquid and vapor phases, along with the saturation line and the critical poi
yarga [219]

Answer:

Pressure- temperature diagram of the fluid is the phase lines that separate all the phases.

Explanation:

Step1

Pressure temperature diagram is the diagram that represents the all the phases of the fluid by separating a line. There is no phase change region in the pressure temperature diagram out of 15 possible diagrams. There are three lines that separate the phase of the fluid. These three lines are fusion, vaporization and sublimation.

Step2

The intersecting point of these lines is triple point of fluid. Out of 15 possible phase diagram, only pressure temperature diagram has triple point as a point. In other diagrams phase change region is present and triple point is not a point. Critical point is the point in all possible property diagrams.

Pressure temperature diagram is shown below:

You have a 12-inch PVC water main that is 850 feet long flowing at 5.6 cfs. Point A is at an elevation of 750 ft. Point B is at
alex41 [277]

Known :

D = 12 in = 1 ft

L = 850 ft

Q = 5.6 cfs

hA = 750 ft

hB = 765 ft

PA = 85 psi = 12240 lb/ft²

Solution :

A = πD² / 4 = π(1²) / 4

A = 0.785 ft²

<u>Velocity of water :</u>

U = Q / A = 5.6 / 0.785

U = 7.134 ft/s

<u>Friction loss due to pipe length :</u>

Re = UD / v = (7.134)(1) / (0.511 × 10^(-5))

Re = 1.4 × 10⁶

(From Moody Chart, We Get f = 0.015)

hf = f(L / d)(U² / 2g) = 0.015(850 / 1)((7.134²) / 2(32.2))

hf = 10 ft

PA + γhA = PB + γhB + γhf

PB = PA + γ(hA - hB - hf)

PB = 12240 + (62.4)(750 - 765 - 10)

PB = 10680 lb/ft²

PB = 74.167 psi
