His is a step down transformer since n(primary) is greater than n(seconcary). You relate the input voltage with the ouput voltage with the following equation:
<span>Vout = n2/n1*Vin (n2/n1 is essentially your 'transfer function' that dictates what a specified input would produce) </span>
<span>Solving the equation: </span>
<span>Vin = Vout*n1/n2 = (320V)*(600/300) = 640 V </span>
<span>This is checked by seeing if Vin is greater than Vout, which it is for a step down transformer.</span>
P = 10^5 - ρ (average)gh
where ρ (average) = average air density between 0 and 5000 m = (1.22+0.74)/2 = 0.98
we know g & h
I get P = 52470 Pa
An additional 10ppm of methane will change the upward IR heat flux (in tropical
atmosphere) from 289.29 W/m2
to 286.211 W/m2
, which is a reduction of 3.08
W/m2
.
An additional 10ppm of CO2 will change the upward IR heat flux from 289.29 W/m2
to 289.29 W/m2
, which is a change of 0.13 W/m2
.
Therefore, an additional 10 ppm of methane would have a much larger impact on
the outgoing infrared flux than an additional 10 ppm of CO2 at current
concentrations
