To solve this process it is necessary to consider the concepts related to the relations between pressure and temperature in an adiabatic process.
By definition the relationship between pressure and temperature is given by
![(\frac{P_2}{P_1})=(\frac{T_2}{T_1})^{(\frac{\gamma}{\gamma-1})}](https://tex.z-dn.net/?f=%28%5Cfrac%7BP_2%7D%7BP_1%7D%29%3D%28%5Cfrac%7BT_2%7D%7BT_1%7D%29%5E%7B%28%5Cfrac%7B%5Cgamma%7D%7B%5Cgamma-1%7D%29%7D)
Here
P = Pressure
T = Temperature
The ratio of specific heats. For air normally is 1.4.
Our values are given as,
![P_1 = 15lb/in^2\\T_1= 80\°F = 299.817K\\T_2 =400\°F = 408.15K](https://tex.z-dn.net/?f=P_1%20%3D%2015lb%2Fin%5E2%5C%5CT_1%3D%2080%5C%C2%B0F%20%3D%20299.817K%5C%5CT_2%20%3D400%5C%C2%B0F%20%3D%20408.15K)
Therefore replacing we have,
![(\frac{P_2}{P_1})=(\frac{T_2}{T_1})^{(\frac{\gamma}{\gamma-1})}](https://tex.z-dn.net/?f=%28%5Cfrac%7BP_2%7D%7BP_1%7D%29%3D%28%5Cfrac%7BT_2%7D%7BT_1%7D%29%5E%7B%28%5Cfrac%7B%5Cgamma%7D%7B%5Cgamma-1%7D%29%7D)
![(\frac{P_2}{15})=(\frac{408.15}{299.817})^{(\frac{1.4}{1.4-1})}](https://tex.z-dn.net/?f=%28%5Cfrac%7BP_2%7D%7B15%7D%29%3D%28%5Cfrac%7B408.15%7D%7B299.817%7D%29%5E%7B%28%5Cfrac%7B1.4%7D%7B1.4-1%7D%29%7D)
Solving for ![P_2,](https://tex.z-dn.net/?f=P_2%2C)
![P_2 = 15*(\frac{408.15}{299.817})^{(\frac{1.4}{1.4-1})}](https://tex.z-dn.net/?f=P_2%20%3D%2015%2A%28%5Cfrac%7B408.15%7D%7B299.817%7D%29%5E%7B%28%5Cfrac%7B1.4%7D%7B1.4-1%7D%29%7D)
![P_2 = 44.15Lbf/in^2](https://tex.z-dn.net/?f=P_2%20%3D%2044.15Lbf%2Fin%5E2)
Therefore the maximum theoretical pressure at the exit is ![44.15Lbf/in^2](https://tex.z-dn.net/?f=44.15Lbf%2Fin%5E2)
Answer:
a)48900 metros
b)0.36875 metros
c)75634 metros
d)9.876 metros
Explanation:
Hola, para resolver debemos convertir unidades utilizando equivalencias
a) 48.9 km
1 kilometro = 1000 metros
48.9 x 1000 = 48900 metros
b) 36.875 cm
1 centímetro =0.01 metros
36.875 x 0.01 = 0.36875 metros
c) 756,34 hm
1 hectómetro= 100 metros
756.34 x 100 = 75634 metros
d) 9876 mm
1 milímetro = 0.001 m
9876 x 0.001 = 9.876 metros
