Ammonia at 70 F with a quality of 50% and a total mass of 4.5 lbm is in a rigid tank with an outlet valve at the bottom. How muc

Inessa05 [86]

Answer:

0.10865 killograms

Step-by-step explanation:

calculating the liquid mass of ammonia removed through the bottom value from a rigid tank at constant temperature.

Given:

temperature: $T=70 F$

quality : 50% = 0.5

initial mass: $m1= 4.5 lbm$

to find the removed liquid mass first we have to find total volume from which we can find remaining mass. as the tang is rigid the temperature and volume remains constant.

by taking the difference of mass we can determine the mass of liquid removed.

we have two phases at temperature $T= 70 F$ with specific volume for liquid $vf=0.02631 ft^3/lbm$ and specific volume for vapor is $vg=2.3098 ft^3/lbm$ .

The Volume in the initial state is given by, (Using definition of specific volume)

$V= m1v1$

using $v1=x(vf+vg)$

$V= m1x(vf+vg)$

substituting $m1= 4.5 lbm\\$ , $vf= 0.02631 ft^3/lbm$ , $vg=2.3098 ft^3/lbm$

we get

$V= (4.5 lbm)(0.5)(0.02631 ft^3/lbm +2.3098 ft^3/lbm)$

finally $V=5.2625 ft^3$

we know the formula to find liquid mass is

$mass =density *volume$

density of ammonia is $0.73 kg/m^3$

inserting the values into the formula we get the value for liquid mass removed through the valve.

$m = (0.73 kg/m^3)*(5.25625 ft^3)$

the final answer is

$m= 0.10865 kg$

6. slope = -1; y-intercept = 8<br> Write the linear equation in slope intercept form

Mice21 [21]

Answer: y = -1x + 8

Step-by-step explanation: linear equations must be written in the format

y = mx + b from.

m represents the slope which it -1

b represents the y-intercept which is 8.

Just substitute the slope and y-intercept in the m and b places and that is a linear equation.

Vanessa works 32 hours per week at her job. Her boss offers her a full time job (40 Hours per week) and a 2 dollar per hour rais

FinnZ [79.3K]

Answer:

$35.75 per hour

Step-by-step explanation:

In order to calculate this, we first need to calculate how much she made with her current hourly wage. We do this by multiplying the hours she worked by her current hourly wage plus her raise.

32 hours * (40+2) = $1,344

Now we subtract $200, since this is how much more she is making with her raise, and then we divide that amount by the 32 hours she is working per week.

(1,344 - 200) / 32 = $35.75 per hour

Finally, we can see that Vanessa's hourly wage before the raise was $35.75 per hour
