Answer:
exergy = 33.39 kW
Explanation:
given data
thermal energy reservoir T2 = 1500 K
heat at a rate = 150,000 kJ/h = 
kW = 41.67 kW
environment temperature T1 = 25°C = 298 K
solution
we get here maximum efficiency that is reversible efficiency is express as
reversible efficiency = 1 - 
...............1
reversible efficiency = 1 - 
reversible efficiency = 0.80133
and
the exergy of this supplied energy that is
exergy = efficiency × hat supply ................2
exergy = 0.80133 × 41.67 kW
exergy = 33.39 kW

Explanation:
A lower triangular matrix is one whose elements above the main diagonal are zero meanwhile all the main diagonals elements and below are nonzero elements. This is one of the two existing types of triangular matrixes. Attached you will find a image referring more about triangular matrixes.
If there is any question, just let me know.
The EMV - Ending Market Value is given as:
$2,400,000.
<h3>How is the EMV Arrived At?</h3>
The EMV is given as:
BMV x (i + r); Where
BMV is the Beginning Market Value; and
r is the interest rateor percentage given.
Hence the EMV = 2,000,000 x ( 1 + 20%)
= 2,000,000 x 1.2
= $ 2, 400,000.
It is to be noted that the BMV is the Beginning Market Value which is the value of an investment at the start of the business period.

Answer:
Yes the water will be safe at the point of cooling water discharge
Explanation:
Power losses in plant= 350- 350×0.35=227.5MW
Rate of heat rejection to stream= 0.75× 227.5= 170.625MW
Rate of heat rejection= rate of flow of water× c × ΔT
170625000= 150000000× 4.186 × (Final temperature- 20)
Final temperature= 20.3 ◦C
The final temperature of stream will be 20.3 ◦C. Thechange is very small so the minnows will be able to handle this temperature.
Answer:
The 21st century world have been earmarked with great influx of people to the urban centre,the notion of gender equality and female education have also made most traditional roles in the family changing.Before now,wives we're known for their full independence on their husband who is considered the bread winner.
