Answer:

x = 12

Step-by-step explanation:

When y = 16, to solve for x we can write:

16 = 25/6x - 34

50 = 25 / 6 x (Add 34)

x = 12 (Divide by 25/6)

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

$m= 0.10865 kg$

Which function produces an output of 5 for an input of -6?

kodGreya [7K]

Answer:

The answer is D

Step-by-step explanation:

Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)
