Answer:
The answer is "
"
Explanation:
Given data:
Initial temperature of tank 
Initial pressure of tank 
Diameter of throat 
Mach number at exit 
In point a:
calculating the throat area:
Since, the Mach number at throat is approximately half the Mach number at exit.
Calculate the Mach number at throat.
Calculate the exit area using isentropic flow equation.
Here: 
is the specific heat ratio. Substitute the values in above equation.
exit diameter is 3.74 cm
In point b:
Calculate the temperature at throat.
Calculate the velocity at exit.
Here: R is the gas constant.
Calculate the density of air at inlet
Calculate the density of air at throat using isentropic flow equation.
Calculate the mass flow rate.
Maybe because of shipping costs and if you need to buy materials from a far place such as different international travels?
<u>A Problem Statement:</u>
A problem statement is away from the depiction of the issue(s) that need(s) to be tended to by a critical thinking group. It plainly states what circumstance you're managing, why it's an issue, and what your optimal state would be. A straightforward and very much characterized issue proclamation will be utilized by the task group to comprehend the issue and work toward building up an answer.
An issue articulation is typically a couple of sentences to clarify the issue your procedure improvement task will address. When all is said in done, an issue explanation will plot the negative purposes of the present circumstance and clarify why these issues. Issue articulations frequently have three components: the issue itself, expressed obviously and with enough logical detail to set up why it is significant; the technique for taking care of the issue, regularly expressed as a case or a working proposal; the reason, explanation of goal and extent of the report the author is getting ready.
Answer:
800°C
Explanation:
Phase diagram of an alloy is a graphical presentation showing the phases compositions and their relative amounts at any different temperature and under equilibrium conditions. It is used to predict the phase changes of the alloys at different temperatures.
From the figure, we can see that the tie lines are proportional about α + L at a temperature of 800°C for
