Explanation:

It could either be true or false because you dont really have to be great at something just to do it, you could try new things too.

Kisachek [45]

Answer:

True, True

Explanation:

1st Scenario: Purchase of new contamination equipment would indicate that the plant had been violating environmental regulations and reporting false data. So, Cathy and Henry must not purchase and install new contamination equipment unless the data indicates serious violatino of environmental regulations.

2nd Scenario: Company has the responsibiltiy to report contamination in plant water to regulatory agencies and Cathy Martin has been assigned this responsibility to report on behalf of the company. Reporting "adjusted" or inaccurate data is against the business ethics. So, professionally Cathy Martin is responsible for her reports to regulatory agencies.

4.In a hydroelectric power plant, 100 m3/s of water flows from an elevation of 120 m to a turbine, where electric power is gener

Dmitrij [34]

Answer:

The rate of irreversible loss will be "55.22 MW".

Explanation:

The given values are:

Elevation,

h = 120 m

Flow of water,

Q = 100 m³/s

Efficiency,

= 80%

i.e,

= 0.8

Efficiency turbine,

= 50 MW

Now,

Without any loss,

The power generated by turbine will be:

⇒ $P=\delta gQh$

On substituting the values, we get

⇒ $=1000\times 9.8\times 100\times 120$

⇒ $=117.72 \ MW$

Power generated in actual will be:

= $\frac{50}{0.8}$

= $62.5 \ MW$

Hence,

Throughout the piping system,

The rate of irreversible loss is:

= $Power \ generated \ by \ turbine-Power \ generated \ in \ actual$

= $117.72-62.5$

= $55.22 \ MW$

Propane is to be compressed from 0.4 MPa and 360 K to 4 MPa using a two-stage compressor. An interstage cooler returns the tempe

kow [346]

Answer:

a. 81 kj/kg

b. 420.625K

c. 101.24kj/kg

Explanation:

$\frac{t2}{t1} =[\frac{p2}{p1} ]^{\frac{y-1}{y} }$

t1 = 360

p1 = 0.4mpa

p2 = 1.20

y = 1.13

substitute these values into the equation

$\frac{t2}{360} =[\frac{1.20}{0.4} ]^{\frac{1.13-1}{1.13} }$

$\frac{t2}{360} =[\frac{1.2}{0.4} ]^{0.1150}\\\frac{t2}{360} =1.1347$

when we cross multiply

t2 = 360 * 1.1347

= 408.5

a. the work required in the firs compressor

w=c(t2-t1)

c=1.67x10³

t1 = 360

t2 = 408.5

w = 1670(408.5-360)

= 1670*48.5

= 80995 J

= 81KJ/kg

b. $n=\frac{t2-t1}{t'2-t1}$

n = 80%

t2 = 408.5

t1 = 360

0.80 = 408.5-360 ÷ t'2-360

$0.80 =\frac{48.5}{t'2-360}$

cross multiply to get the value of t'2

0.80(t'2-360) = 48.5

0.80t'2 - 288 = 48.5

0.8t'2 = 48.5+288

0.8t'2 = 336.5

t'2 = 336.5/0.8

= 420.625

this is the temperature at the exit of the first compressor

c. cooling requirement

w = c(t2-t1)

= 1.67x10³(420.625-360)

= 1670*60.625

= 101243.75

= 101.24kj/kg

Write a function M-file that takes as input two matrices A and B, and as output produces the product by columns of the two matri

docker41 [41]

Answer:

Here is the code in Matlab for the function.

I have also attached the m file for function as well as the test run of the code here and screenshot of the result.

Code:

function [ C ] = columnproduct( A, B )

% get the dimesnions of A

sizeA = size(A);

sizeB = size(B);

% check if columns of A are same as rows of B

if(sizeA(2) ~= sizeB(1))

error('matrix dimensions do not match')

end

% initialize resultant matrix

C = [];

for i = 1:sizeB(2)

% concatenating product of matrix A with each column of B

C = [C A*B(:,i)];

end
