Answer
given,
P₁ = 8 bar T₁ = 500 K V₁ = 150 m/s
P₂ = 1 bar T₂ = 320 K V₂ = 10 m/s
writing energy equation
h₁ + (KE)₁ + (PE)₁ + Q m = h₂ + (KE)₂ + (PE)₂ + W
![W = (h_1 - h_2 ) + \dfrac{V_1^2-V_2^2}{2000}](https://tex.z-dn.net/?f=W%20%3D%20%28h_1%20-%20h_2%20%29%20%2B%20%5Cdfrac%7BV_1%5E2-V_2%5E2%7D%7B2000%7D)
ideal gas property of air
T₁ = 500 K h₁ = 503.02 KJ/kg S₁ = 2.21952 kJ/kgK
T₂ = 320 K h₂ = 320.29 KJ/kg S₂ = 1.7679 kJ/kgK
![W = (503.02-320.29) + \dfrac{150^2-10^2}{2000}](https://tex.z-dn.net/?f=W%20%3D%20%28503.02-320.29%29%20%2B%20%5Cdfrac%7B150%5E2-10%5E2%7D%7B2000%7D)
W = 193.93 KJ/Kg
calculation of energy destruction
= ![T_0(S_2-S_1-Rln(\dfrac{P_2}{P_1}))](https://tex.z-dn.net/?f=T_0%28S_2-S_1-Rln%28%5Cdfrac%7BP_2%7D%7BP_1%7D%29%29)
= ![T_0(S_2-S_1+Rln(\dfrac{P_1}{P_2}))](https://tex.z-dn.net/?f=T_0%28S_2-S_1%2BRln%28%5Cdfrac%7BP_1%7D%7BP_2%7D%29%29)
= ![300(1.7679-2.21952-\dfrac{8.314}{28.97}ln(\dfrac{8}{1}))](https://tex.z-dn.net/?f=300%281.7679-2.21952-%5Cdfrac%7B8.314%7D%7B28.97%7Dln%28%5Cdfrac%7B8%7D%7B1%7D%29%29)
=![300 \times 0.145152](https://tex.z-dn.net/?f=300%20%5Ctimes%200.145152)
=43.54 KJ/Kg
The engineering design process is a common series of steps that engineers use in creating functional products and processes.
Steps of the Engineering Design Process
Define the Problem. The engineering design process starts when you ask the following questions about problems that you observe: ...
Do Background Research. ...
Specify Requirements. ...
Brainstorm Solutions. ...
Choose the Best Solution. ...
Develop the Solution. ...
Build a Prototype. ...
Test and Redesign.
Process Engineer responsibilities include:
Developing, configuring and optimizing industrial processes from inception through to start up and certification. Assessing processes, taking measurements and interpreting data. Designing, running, testing and upgrading systems and processes.
