Explanation:
Expression for energy balance is as follows.
or, 
Therefore,
Hence, expression for exit velocity will be as follows.
= ![V^{2}_{1} + 2C_{p}(T_{1} - T_{2})]^{0.5}](https://tex.z-dn.net/?f=V%5E%7B2%7D_%7B1%7D%20%2B%202C_%7Bp%7D%28T_%7B1%7D%20-%20T_%7B2%7D%29%5D%5E%7B0.5%7D)
As 
for the given conditions is 1.007 kJ/kg K. Now, putting the given values into the above formula as follows.
![V_{2} = V^{2}_{1} + 2C_{p}(T_{1} - T_{2})]^{0.5}](https://tex.z-dn.net/?f=V_%7B2%7D%20%3D%20V%5E%7B2%7D_%7B1%7D%20%2B%202C_%7Bp%7D%28T_%7B1%7D%20-%20T_%7B2%7D%29%5D%5E%7B0.5%7D)
= ![[(350 m/s)^{2} + 2(1.007 kJ/kg K) (30 - 90) K \frac{1000 m^{2}/s^{2}}{1 kJ/kg}]^{0.5}](https://tex.z-dn.net/?f=%5B%28350%20m%2Fs%29%5E%7B2%7D%20%2B%202%281.007%20kJ%2Fkg%20K%29%20%2830%20-%2090%29%20K%20%5Cfrac%7B1000%20m%5E%7B2%7D%2Fs%5E%7B2%7D%7D%7B1%20kJ%2Fkg%7D%5D%5E%7B0.5%7D)
= 40.7 m/s
Thus, we can conclude that velocity at the exit of a diffuser under given conditions is 40.7 m/s.
Answer:
Explanation:
Appears to be the vertexes of a triangle.
AB = √(-6 - (-2))² + (3 - 4)²) = √17
AC = √(-6 - (-8))² + (3 - 3)²) = 2
BC = √(-2 - (-8))² + (4 - 3)²) = √37
Answer:
the pearls have an electrical charge induced by contact with the ions of the solution and these charges are attracted by the electrode by a force electric
Explanation:
The pearls are suspended in a solution, when connecting the power source, it is subjected to an electric shock, the pearls have an electrical charge induced by contact with the ions of the solution and these charges are attracted by the electrode by a force electric
F = q E
Answer:
A. These vibrations can travel through solids, liquids, and gases, but not through <u>empty</u><u> </u><u>space</u>.
Answer:
0.557 s
Explanation:
Given:
v₀ = 5.46 m/s
v = 0 m/s
a = -9.8 m/s²
Find: t
v = at + v₀
0 m/s = (-9.8 m/s²) t + 5.46 m/s
t = 0.557 s
