How far would a horse that rides at 8.1 m/s travel and 8.5 minutes

Xelga [282]

V = S/t

The time is in minutes, it needs to be converted to seconds, because the Velocity 8.1meters/second.

1 min -------- 60 secs
8.5 min -------- x secs
-> x = 8.5 . 60
-> x = 510secs

-> 8.1 = S/510
-> 510 x 8.1 = S
-> S = 4131 meters

An airplane is flying at 300 mi/h at 4000 m standard altitude. As is typical, the air velocity relative to the upper surface of

posledela

Answer:

57330.17766 Pa

Explanation:

$P_1$ = Pressure at 4000 m = 61660 Pa

$\rho$ = Density at 4000 m = 0.8194 kg/m³

(Values taken from table of properties of air)

$V_1$ = Velocity of jet = $300\times \frac{1609.34}{3600}=134.11\ m/s$

$V_2$ = Velocity at max thickness

$V_2=1.26V_1=1.26\times 134.11=168.9786\ m/s$

From Bernoulli's equation

$P_1+\frac{1}{2}\rho V_1^2=P_2+\frac{1}{2}\rho V_2^2\\\Rightarrow P_2=P_1+\frac{1}{2}\rho V_1^2-\frac{1}{2}\rho V_2^2\\\Rightarrow P_2=61660+\frac{1}{2}\times 0.8194\times 134.11^2-\frac{1}{2}\times 0.8194\times 168.9786^2\\\Rightarrow P_2=57330.17766\ Pa$

The absolute pressure at this point on the wing is 57330.17766 Pa
