At a given point in a supersonic wind tunnel, the pressure and temperature are 5×104 N/m2 and 200 K, respectively. The total pre

Ne4ueva [31]

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

aliina [53]

Answer:

(i) 3.5385 ohm, 3.768 ohm (ii) 39.89 A (III) 4773.857 W (vi) 348 var (vii) 0.9973 (viii) 4.1796°

Explanation:

We have given voltage V =120 volt

Frequency f=60 Hz

Resistance R =3 ohm

Inductance L =0.01 H

Capacitance C =0.00075 farad

(i) reactance of of inductor $X_L=\omega L=2\pi fL=2\times 3.14\times 60\times 0.01=3.768ohm$

$X_C=\frac{1}{\omega C}=\frac{1}{2\times 3.14\times 60\times 0.00075}=3.5385ohm$

(ii) Total impedance $Z=\sqrt{R^2+(X_L-X_C)^2}=\sqrt{3^2+(3.768-3.5385)^2}=3.008ohm$

Current $i=\frac{V}{Z}=\frac{120}{3.008}=39.89A$

(viii) power factor $cos\Phi =\frac{R}{Z}=\frac{3}{3.008}=0.9973$

(VII) $cos\Phi =0.9973$

$\Phi =4.1796^{\circ}$

So power factor angle is 4.1796°

(iii) Apparent power $P=VICOS\Phi =120\times 39.89\times 0.9973=4773.875W$

(vi) Reactive power $Q=VISIN\Phi =120\times 39.89\times SIN4.17^{\circ}=348var$
