Well h=u+pv, with u being the internal energy and p pressure and volume is constant for the tank.

Homework Statement Given a tank filled with gas, you are to pump out a given amount and find the final state of the tank. Given the volume, gas (non-ideal), amount of gas in tank, flow rate, temperature and pressure, all at state 1. We can find density at state 2 from the tables, but we need...

Hello all, I am having a problem with this question. Can not see what I am doing wrong. Homework Statement Show that the two expressions are equivalent, by construction a rotation matrix Rsi. S = (-R sin(a*a_dot) - w R sin(a))s1 + (R cos(a*a_dot) + w R cos(a))s2 I = (-R...

Hello, I am in my 3rd semester at college, I have take Calculus 1,2,3 (derivatives, integrals, vector calculus) and linear algebra and next semester will be differential equations. I want to do some sort of a paper or a research project in the mathematical field. At school we do not have...

Hi, I am a college freshman and have taken Calculus I,II,III (covering derivatives, integrals, series and vectors) while going over my book during the summer I tried doing several problems from random chapters. Most of which were application or physics related. Most of these I was not able to...

Hello, This summer I would be interested in designing my own model rocket. I do not have a lot of aerospace/aerodynamics (read the NASA (http://www.grc.nasa.gov/WWW/k-12/airplane/)) knowledge but I do have a good grasp of math and physics. I would like to use a A or B model rocket engine and...
