Answer:
A) ≥ 325Kpa
B) ( 265 < Pe < 325 ) Kpa
C) (94 < Pe < 265 )Kpa
D) Pe < 94 Kpa
Explanation:
Given data :
A large Tank : Pressures are at 400kPa and 450 K
Throat area = 4cm^2 , exit area = 5cm^2
<u>a) Determine the range of back pressures that the flow will be entirely subsonic</u>
The range of flow of back pressures that will make the flow entirely subsonic
will be ≥ 325Kpa
attached below is the detailed solution
<u>B) Have a shock wave</u>
The range of back pressures for there to be shock wave inside the nozzle
= ( 265 < Pe < 325 ) Kpa
attached below is a detailed solution
C) Have oblique shocks outside the exit
= (94 < Pe < 265 )Kpa
D) Have supersonic expansion waves outside the exit
= Pe < 94 Kpa
Answer:
it's important because it shows how thermal energy transforms or continues to be all around us in everything
A its Stratosphere, Sorry I didn't see your answer, its bilogy I think not physics.. :)
Answer:
It works by adding an engine, a transmission, car batteries, an extra strong frame in case of a crash, and much more needed things. When it races, The rubber often burns a lot, because of the high speeds that it goes, so that is why they so often change the tires. They give it a full tank of gas, which is basically like the car's idea of food and water. A NASCAR must have a trong engine to go so fast in order to win a race.
Explanation:
Just think of it like building a lego car just hot gluing the legos together and seeing if it breaks.
