Answer:

Cost = $2527.2 per month.

Explanation:

Given that

Discharge ,Q = 130 L/min

$Q=0.13\ m^3/min$

Cost = $0.45 per cubic meter

1 month = 30 days

1 days = 24 hr = 24 x 60 min

1 month = 30 x 24 x 60 min

1 month = 43,200 min

Lets x $m^3\ water\ waste\ in\ a\ month$

x = 0.13 x 43,200

$x=5616\ m^3$

So the total cost = 5616 x 045 $

Cost = $2527.2 per month.

Consider two different types of motors. Motor A has a characteristic life of 4100 hours (based on a MTTF of 4650 hours) and a sh

Daniel [21]

Answer:B

Explanation:

Given

For motor A

Characteristic life(r)=4100 hr

MTTF=4650 hrs

shape factor(B )=0.8

For motor B

Characteristic life(r)=336 hr

MTTF=300 hr

Shape Factor (B)=3

Reliability for 100 hours

$R_a=e^{-\left ( \frac{T-r}{n}\right )B}$

$R_a=e^{-\left ( \frac{4650-4100}{100}\right )0.8}$

$R_a=e^{-4.4}=0.01227$

For B

$R_b=e^{-\left ( \frac{300-336}{100}\right )3}$

$R_b=e^{1.08}=2.944$

B is better for 100 hours

(b)For 750 hours

$R_a=e^{-0.5866}=0.55621$

$R_b=e^{0.144}=1.154$

So here B is more Reliable.

natta225 [31]

Answer:

Option c)

Explanation:

a.The carbon content of eutectoid steel, which is an carbon- iron alloy, is in between 0.80-0.83%

b. In hypoeutectoid steel, the carbon composition is less than 0.80% and is approximately 0.76%

c. In hypereutectoid steel, the carbon composition ranges from 0.80% - 2.0%

d. In wrought iron, the iron composition is quite low about 0.08%
