Thank you! I've always been under the assumption to never use ideal gas for non ideal gases though? This is a first for me. Is there a way to know? Thanks again
Homework Statement
Okay, so these are usually pretty easy for me to understand, but this one doesn't make sense.
10 kg of water in a piston cylinder arrangement exists as saturated liquid/vapor at 100 kPa, with a quality of 50%. It is now heated so the volume triples. The mass of the piston is...
So that sounds fine? That was my general idea in my first one I was just assuming the cloud to be a cylinder for some reason. Thanks for the help everyone. I'm still coming up with 2.84 * 10^10 lb so I guess I'll give that a shot.
Okay so this is what I've come up with. The area of the cloud is equal to volume/height = 9.57 * 10^11 ft^3 / 350 ft = 2.73 * 10^9 ft^2
Area of barrel = 28.3 ft^2
Volume water in barrel = 4.72 ft^3
Weight water in barrel = 294 lb
Barrels that fit in area of cloud = 9.65 * 10^7
Total weight =...
Homework Statement
The rain cloud has an approximate volume of 6.50 mile3and an average height, top to bottom, of 350 ft.1 mile = 5280 ft.
If a cylindrical container 6 ft in diameter collects 2 in. of water after the rain falls out of the cloud, estimate the total weight of rain that fell from...
Homework Statement
If the bulk modulus for water at
70∘F is 319 kip/in^2, determine the change in pressure required to reduce its volume by 0.3%.
Homework Equations
E = dP/(dV/V)
E - Bulk Modulus
dP - change in pressure
dV - change in volume
V - volume

Well I just...
In our problems with nozzles, I believe we are assuming the following:
closed system
steady state (de/dt = 0)
W = 0
Q = 0
PE = 0
I have emailed my teacher regarding the problem with the areas. I figured she must have left m out on accident. I just wanted to come on here and make sure. Thanks...
Homework Statement
In a jet engine, a flow of air at 1000 K, 200 kPa, and 40 m/s enters a nozzle, where the air exits at 500 m/s and 90 kPa. What is the exit temperature, inlet area, and exit area, assuming no heat loss?
Homework Equations
min = mout = m
where m = mass air flow
dE/dt cv = Qcv...
Hey guys, this still is unanswered, I could really use some help. Please?
Given:
specific volume (v1) = 1 m3/kg - ideal gas
P1 = 760 kPa
P2 = 350 kPa
Find specific work.
Sorry to nag, I just really want to know how to do this.
Okay so if I have 1 m3/kg of an ideal gas, the mass density of that gas is 1 kg/m3, what do I do with that and how does that get me to find my work? I've manipulated the equations as much as I know how and now I'm even more lost than I was when I posted this problem.
Oh alright I'll remember that. I just have it written down differently. Unfortunately, that's all I'm given. Maybe there was a typo and she meant to just say work instead of specific work?
