Answer:
Explanation:
We have to many data in different system, so we need transform everything to SI, that is
When we have all this values in SI apply a Energy Balance Equation,
![\dot{Q}_{cv}-\dot{W}_{cv}+\dot{m}[(h_1-h_2)+(\frac{V_1^2-V_2^2}{2})+g(z_1-z_2)]=0](https://tex.z-dn.net/?f=%5Cdot%7BQ%7D_%7Bcv%7D-%5Cdot%7BW%7D_%7Bcv%7D%2B%5Cdot%7Bm%7D%5B%28h_1-h_2%29%2B%28%5Cfrac%7BV_1%5E2-V_2%5E2%7D%7B2%7D%29%2Bg%28z_1-z_2%29%5D%3D0)
Solving for V_2
From the table of gas properties we calculate for 
and 
For T_2;
Substituting in equation for V_2

Answer;
3.45 × 10^-1
Explanation;
-Here we wish to write the number 0.345 as a coefficient times 10 raised to an exponent. To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45.
-The number of places to the left that you had to move the decimal point is the exponent.
= 0.345
= 3.45/10
= 3.45 × 10^-1
Fire extinguishers are typically red. Goes along with the red fire trucks and red being a color of emergency. While there isn't any standard, if we decided to change the colors of the fire extinguisher, people would be very confused and given the context, it could cost people's lives, so I'm thinking red will be the color of fire extinguishers for a while to come.
