Answer:
for m1=0.2
M2=0.4
for m1=2.5
M2=5
1= channel input
2.channel output
Explanation:
Hello!
To solve this problem follow the steps below!
1.As it is an isentropic system, it means that the temperature of the fluid remains constant, so the volumetric flow is the same, remember that this is calculated by calculating the product between the velocity and the area.
V1A1=V2A2
1= channel input
2.channel output
We can divide both sides of the equation by the speed of sound(V)
2. The mach number is defined as the ratio between the speed of a fluid and the speed of sound,
we rearrange the equation
M1A1=M2A2
3.Now considering that the channel is convergent and that the ratio between the areas is 2, we have the following equation (A1 / A2 = 2)
M1(2)=M2
4.Finally we solve for the number of mach indicated (0.2 and 2.5)
for m1=0.2
0.2(2)=M2=0.4
for m1=2.5
2.5(2)=M2=5
Answer:
b. A view of a building seen from one side, a flat representation of one façade. This is the most common view used to describe the external appearance of a building.
Explanation:
An elevation is a three-dimensional, orthographic, architectural projection that reveals just a side of the building. It is represented with diagrams and shadows are used to create the effect of a three-dimensional image.
It reveals the position of the building from ground-depth and only the outer parts of the structure are illustrated. Elevations, building plans, and section drawings are always drawn together by the architects.
Answer:
amount of electric charge transported = 1.13 × 
C
Explanation:
given data
electric current = 237.0 mA = 0.237 A
time = 8 min = 8 × 60 sec = 480 sec
solution
we get here amount of electric charge transported that is express as
amount of electric charge transported = electric current × time ...........1
put here value and we get
amount of electric charge transported = 0.237 × 480
amount of electric charge transported = 113.76 C
amount of electric charge transported = 1.13 × C
