Suppose the working pressure for a boiler is 10 psig, then what is the corresponding absolute pressure?

yanalaym [24]

Answer:

The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.

Explanation:

From Fluid Mechanics, we remember that absolute pressure ( $p_{abs}$ ), measured in pounds per square inch, is the sum of the atmospheric pressure and the working pressure (gauge pressure). That is:

$p_{abs} = p_{atm}+p_{g}$ (1)

Where:

$p_{atm}$ - Atmospheric pressure, measured in pounds per square inch.

$p_{g}$ - Working pressured of the boiler (gauge pressure), measured in pounds per square inch.

If we suppose that $p_{atm} = 14.696\,psi$ and $p_{g} = 10\,psi$ , then the absolute pressure is:

$p_{abs} = 14.696\,psi+10\,psi$

$p_{abs} = 24.696\,psi$

The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.

For some transformation having kinetics that obey the Avrami equation (Equation 10.17), the parameter n is known to have a value

OleMash [197]

Answer:

t = 25.10 sec

Explanation:

we know that Avrami equation

$Y = 1 - e^{-kt^n}$

here Y is percentage of completion of reaction = 50%

t is duration of reaction = 146 sec

so,

$0.50 = 1 - e^{-k^146^2.1}$

$0.50 = e^{-k306.6}$

taking natural log on both side

ln(0.5) = -k(306.6)

$k = 2.26\times 10^{-3}$

for 86 % completion

$0.86 = 1 - e^{-2.26\times 10^{-3} \times t^{2.1}}$

$e^{-2.26\times 10^{-3} \times t^{2.1}} = 0.14$

$-2.26\times 10^{-3} \times t^{2.1} = ln(0.14)$

$t^{2.1} = 869.96$

t = 25.10 sec

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>
