Answer:

The Mach number is 2.866

Total temperature To = 528.524K

Explanation:

Pressure (P)= 5 * 10^4 N/m^2

Total pressure (Po) =  1.5 * 10^6 N/m^2

Temperature (T) = 200K

For air, r= 1.4

To find the Mach number we use:

Po/P = [1 + (r - 1/2) M^2] ^ r^/^r^-^1

1.5 * 10^6 / 5 * 10^4 =[ 1 + (1.4 -1 /2) (M^2) ] ^ 1^.^4^/^1^.^4^-^1

0.3 * 10^2 = (1 + 0.2M^2) ^3^.^5

(0.3 * 10^2)^(1/3.5) = 1 + 0.2M^2

2.6426 = 1 +0.2M^2

2.6426 - 1 = 0.2M^2

1.6426 = 0.2M^2

M^2 = 1.6426/0.2

M = sqrt(1.6426/0.2)

M = 2.866

To find Total Temperature :

To/T = (Po/P)^r^-^1^/^8) [tex][tex] To/200 = (1.5*10^6 / 5*10^4)^ 1^.^4^-^1^/^1^.^4)

To/200 = (0.3 * 10^2)^0^.^2^8^5^7

To =528.524K

Consider an infinitely thin flat plate of chord c at an angle of attack α in a supersonic flow. The pressure on the upper and lo
amm1812

Answer:

X_cp = c/2

Explanation:

We are given;

Chord = c

Angle of attack = α

p u (s) = c 1

​p1(s)=c2,

and c2 > c1

First of all, we need to find the resultant normal force on the plate and the total moment about leading edge.

What does the line strung between the batter boards represent?
soldi70 [24.7K]

Batter boards (or battre boards, Sometimes mispronounced as "battle boads") are temporary frames, set beyond the corners of a planned foundation at precise elevations. These batter boards are then used to hold layout lines (construction twine) to indicate the limits (edges and corners) of the foundation.
