#

imo you can't go wrong with most of them lol

#

so wtv you wanna learn more about, do that

#

obvs some cases you might wanna avoid some but generally that is the case

#

for example aerospace engineering for most nationalities it isn't a good idea to study that

mighty pond May 26, 2023, 3:12 PM

#

naive gull for example aerospace engineering for most nationalities it isn't a good idea to...

why is that so

naive gull May 26, 2023, 3:21 PM

#

mighty pond why is that so

with aerospace engineering much of the jobs are in places like nasa for example

#

which in the US is under the department of defense

#

so you must be a US citizen to work there

mighty pond May 26, 2023, 3:21 PM

#

right

#

but a lot of countries have their own space research agencies right?

naive gull May 26, 2023, 3:22 PM

yes

fair enough

naive gull May 26, 2023, 3:23 PM

#

in case you aren't a citizen of one of those countries

#

not sure where he's from

#

also since it's largely government owned

#

the wages

#

could be lower

If pi = 3, and g=10. Does this mean that 3^2 is equal to 10?

If 9=10, I can cancel out the 9 so it's 0=1.

Methanol (CH3OH) is industrially produced from syngas by the following reaction:

The reaction has incomplete conversion. The product CH3OH is condensed, and the unreacted gases CO and H2 are recycled (see the schematics below). It is known that for the overall feed of 1 mol/min CO and 2 mol/min H2 to the process, 0.25 mol/min of CO remains unreacted. The unreacted CO appears in Stream 2 together with other components. Stream 2 is fed into a condenser, from which CO and H2 will be recycled back to the reactor (as Stream 3). Stream 4 is the output from this process and contains pure CH3OH.

Molar mass : MH= 1 g/mol, Mc= 12 g/mol, Mo= 16 g/mol

a)Calculate the production rate of CH3OH in mol/min. What is the overall extent of reaction? Draw a boundary to surround the system for your calculation.
b)If the recycling step is removed, what is the extent of reaction?

inside the reaction vessel, things could be approximated as an equilibrium

define the system as the vessel

and is the free energy of the reaction or the equilibrium constant (at a certain temperature) provided?

W = mg on the planet, so we can find g of that planet! That'll be our vertical acceleration.

Horizontal components:
Sx = 7 m
Ux = U cos(15)
ax = 0

Vertical components:
Sy = 0 m
Uy = U sin(15)
ay = -g

With all these info given, now we'd have to figure out which kinematics equations to use!

#

@fickle sleet try use the horizontal components to find t first, then use t with the vertical components. I think you might have to do a simultaneous substitution

tough willow I need to evaluate this integral using u substitution. Any help?

Try e^3x = u
So you get it in the form:

dx = du/3e^3x

Funky crowbar 1/3 [ 1/4 + u²]du
Factor 4 out of the denominator and the:
1/12 [ 1/1 + (u/2)²]

Multiply the numerator by 0.5
1/6[0.5/1 + 0.25u²]

1/6[tan^-1 (0.5u)] + c
