Question

Please help me I have no clue of what I'm doing now.

Answer 1

The rate at which solar radiation is intercepted by a unit area is called solar heat flux. Just outside the earth's atmosphere, the solar heat flux is approximately 1350 W/m^2. Determine the value of this solar heat flux in units of btu/h*ft^2

Answer 2

@kittiwitti1 I know you hate me putting them here but please help me I promise you the next one i'll put in the box! :)

Answer 3

this is similar to electricity/magnetism flux is it?

Answer 4

I think so I mean its heat flux so yeah man idk this is n engeering question and I suck at this ones more than on the conversations

Answer 5

oh wait, this is just a conversion!

Answer 6

It is? 0_o I got lost with the flux words they were just way off my vocabulary so I start off as 1350W/1m?

Answer 7

yeah

Answer 8

after that is it 1hr/1j?

Answer 9

what is the definition of Watt or wattage

Answer 10

watt = btu/hr

Answer 11

1 btu = 1550 joules

Answer 12

I really have no idea the part throwing me off is the btu/h*ft^2

Answer 13

W = joules/sec

Answer 14

so I should start off as 1350w/1m* first right?

Answer 15

My computer keeps on freezing that's why I drag on replying sometimes or I don't appear on but im still here btw

Answer 16

can you please explain it to me because I do not understand where did you get those numbers from. Or is there a simpler way of showing this conversation?

Answer 18

okay have you taken physics in the past?

Answer 19

noo actually I haven't but I know the simple conversation the ones where you multiply and divide. I don't know this time of conversations

Answer 20

I know how to convert j/kg^C to btu/lbm^f but not this

Answer 21

Can you please show me the log way of conversation with this because it is the only way I undertand it. other than that I cant its too confusing. so the page that you gave me says that the answer is 428

Answer 22

well it would really help if you've taken physics in the past because it allows you to know what the Units are and they are very essential into any conversion

\[1350 \frac{W}{m^2} \rightarrow 1350 \frac{J}{s m^2}\]

Answer 23

im taking it next semester but for now I have no clue what is going on. I even ask for help but this new units are too much

Answer 24

you are being asked to convert it to \[ \frac{BTU}{hr ft } \]

Answer 25

so you need the following information:
how many feet are there in a meter
how many hour is there in a second

Answer 26

and finally how many BTU's are there in a Joule

Answer 27

so there is 1 ft in 1meter and 3600s in a hour

Answer 28

1 ft in 1 m?

Answer 29

3600 SECONDS in an hour
but the question is how many hour is there in a second

Answer 30

none?

Answer 31

there has to be something

Answer 32

half an hour? 1/4 of an hour? think.. laughing out loud

Answer 33

theres nothing not even minutes because a second does not have hours only milliseconds

Answer 34

?

Answer 35

it doesn't make sense to me theres no hours in seconds only milliseconds in a second

Answer 36

\[1 second \times \frac{1minute}{60 seconds} \times \frac{1hour}{60minutes} = x hour\]

Answer 37

notice how the seconds unit cancel out as well the minutes then you are only left with hour?

Answer 38

so theres only 1 hour in a second?

Answer 39

Im really stressed out I honestly do not get this at all. im trying to understand how you did it with the multiplication before but I just don't get it. im honestly so stressed out. then I have another problem left god I just want to shoot myself this is too much.

Answer 40

@nincompoop @nikato @bibby please help me I just can't anymore. I already did try and I got 102 as an answer but its not correct at all

Answer 41

DONT LISTEN TO NINCOMPOOP HE SUCKS SWEATY BALLZ LMFAOOOO

Answer 42

I'm serious right now stop playing I really need help

Answer 43

WELL @nincompoop IS DIRTY AND HOMELESS HOW IS HE GONNA HELP YOU WHEN HE CANT HELP HISSELF?

Answer 44

STOP! I NEED HELP IF YOURE NOT GONNA HELP PLEASE GET OUT!

Answer 45

@f a g how is gonna help himself if he has no job lmfao. he's useless.
