Answer:

system pressure decreases

Explanation:

A relief valve is a device designed to reduce the pressure of a system when it exceeds a maximum pressure established above, it works with a spring that presses a seal when the pressure exceeds the set value the spring deforms, allowing fluid to escape into the atmosphere and decreasing internal pressure.

Considering the above when the spring tension decreases, it means that the system pressure decreases

Answer:

maximum pressure in the system decrease

Explanation:

A spring loaded PSV (pressure safety valve) is a traditional pressure control valve which is designed to work at a predefined pressure and also to safeguard a vessel or framework from large amount of pressure by eliminating or draining fluid from such a system.

The resultant stress on disc is reduced once the inlet pressure is less than the defined pressure and the disc stays positioned in locked position on nozzle. As stress of the system rises to the given amount, the resulting force slowly reduces to zero.

Problem solving is the act of orderly searching for solutions to problem

The correct option that involves approaching a problem in a new way is the option;

Creative thinking

The reasons why creative thinking is the correct option is given as follows;

Finding new ways to approach a problem, involves considering alternatives to already known approaches to the problem

Given that the options to be considered are to be options which have not been applied, then the process does not involve;

Context: Which looks at the variables that relate the problem with setting or circumstance that aid understanding of the problem

Critical thinking; Which is based on the analysis of the known facts, but the new proposals are required

Perseverance; Which involves adherence to a particular option despite delay or difficulty

However;

Creative thinking; Creative thinking involves the consideration of a situation thing or problem in a new way or by approaching a task differently than what was considered a regular approach, which involves finding an unused or imaginative approach to a problem

Therefore;

The option that involves finding new ways to approach a problem is <u>creative thinking</u>

A smooth sphere with a diameter of 6 inches and a density of 493 lbm/ft^3 falls at terminal speed through sea water (S.G.=1.0027

Pachacha [2.7K]

Given:

diameter of sphere, d = 6 inches

radius of sphere, r = $\frac{d}{2}$ = 3 inches

density, $\rho}$ = 493 lbm/ $ft^{3}$

S.G = 1.0027

g = 9.8 m/ $m^{2}$ = 386.22 inch/ $s^{2}$

Solution:

Using the formula for terminal velocity,

$v_{T}$ = $\sqrt{\frac{2V\rho g}{A \rho C_{d}}}$ (1)

$(Since, m = V\times \rho)$

where,

V = volume of sphere

$C_{d}$ = drag coefficient

Now,

Surface area of sphere, A = $4\pi r^{2}$

Volume of sphere, V = $\frac{4}{3} \pi r^{3}$

Using the above formulae in eqn (1):

$v_{T}$ = $\sqrt{\frac{2\times \frac{4}{3} \pir^{3}\rho g}{4\pi r^{2} \rho C_{d}}}$

$v_{T}$ = $\sqrt{\frac{2gr}{3C_{d}}}$

$v_{T}$ = $\sqrt{\frac{2\times 386.22\times 3}{3C_{d}}}$

Therefore, terminal velcity is given by:

$v_{T}$ = $\frac{27.79}{\sqrt{C_d}}$ inch/sec

Answer:

Explanation:

The modern English alphabet is a Latin alphabet consisting of 26 letters, each having an upper- and lower-case form. It originated around the 7th century from Latin script. Since then, letters have been added or removed to give the current Modern English alphabet of 26 letters with no diacritics, diagraphs, and special characters. The word alphabet is a compound of the first two letters of the Greek alphabet, alpha and beta.

Which of these physical concepts is most important in civil engineering?

mezya [45]

Answer:

Option A (energy transformations) is the correct solution.

Explanation:

Energy has become a local matter that has been primarily described as the commitment to deal as well as to generate heat. There are several other power sources, which can either be transferred or transformed to several other renewable technologies.
This same fundamental law defined that the energy required including its universe has been corrected and therefore that energy is being generated as well as severely damaged but should only be moved from one location to the next.

Those certain possibilities are not connected to the circumstance in question. And therefore this answer seems to be the correct one.
