The pilot of an aircraft wishes to fly due west in a 33.9 km/h wind blowing toward the south. The speed of the aircraft in the a
diamong [38]

Answer:\theta =9.96^{\circ} North of west

Explanation:

Given

Plane wishes to fly in west

but wind with speed 33.9 km/h towards south obstructing its path

so plane must fly at an angle of \theta w.r.t west such that it final velocity is towards west

Plane absolute speed=195 km/h

To fly towards west velocity in Y direction should be zero

thus 195sin\theta =33.9

\theta =9.96^{\circ}

so Plane should head towards 9.96^{\circ} North of west in order to fly in west.

So plane

actual velocity is

v=-195cos9.96\hat{i}+195sin9.96\hat{j}

If the humidity in a room of volume 410 m3 at 25 ∘C is 70%, what mass of water can still evaporate from an open pan? Express you
Keith_Richards [23]

Answer:

m=1864.68\ g

Explanation:

Given:

volume of air in the room, V=410\ m^3

temperature of the room, T=25+273=298\ K

<u>Saturation water vapor pressure at any temperature T K is given as:</u>

<u />p_{sw}=\frac{e^{(77.3450 + 0.0057\times T - \frac{ 7235}{T}  )}}{T^{8.2}}<u />

putting T=298 K we have

p_{sw}=3130\ Pa

<u>The no. of moles of water molecules that this volume of air can hold is:</u>

Using Ideal gas law,

P.V=n.R.T

n=\frac{P_{sw}.V}{R.T}

n=\frac{3130\times 410}{8.314\times 298}

n=518\ moles is the maximum capacity of the given volume of air to hold the moisture.

Currently we have 80% of n, so the mass of 20% of n:

m=(20\%\ of\ n)\times M}

where;

M= molecular mass of water

m=0.2\times 518\times 18

m=1864.68\ g is the mass of water that can vaporize further.
