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...

Just wanted to say thanks SteamKing for being so helpful, you've answered stuff for me before.

I figured it should be, but for some reason I kept getting it as just lb or kip. So would the answer be 957 psi? I only have one attempt left.

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 The Attempt at a Solution 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.

She said it was supposed to be 1 m3/kg, so how does this change it? I know that gives us specific volume, not sure what to do with it.

How?

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?
