Answer:
The flow area at the location where the Mach number is 0.9 is 25.24 cm²
Explanation:
Here we have for isentropic flow;
Where:
A = Area of flow = 36 cm²
M = Mach number at section of = 1.8
k = Specific heat ratio = 1.4
A* = Area at the throat
Therefore, plugging the values we get
Therefore, A* = 36/1.439 = 25.01769 cm²
Where the Mach number is 0.9, we have
Therefore A = 25.020× 1.009 = 25.24 cm²
The flow area at the location where the Mach number is 0.9 = 25.24 cm².
The answer is option D.
Area of sheet, A1 = length × breadth
= (8.5 inch * 2.54 cm) ×11 inch * 2.54 cm)
= 603.22
Now, Mass of sheet, M1 = 4.50 gms
Thus, Area of sheet A2, = 1
And, Mass of sheet, M2 = ?
Thus, Mass of M2 =
= 0.0073
