2) an ideal gas flows through a horizontal tube at steady state. no heat is added and no shaft work is done. the cross- sectional area of the tube changes with length and this causes the velocity to change. derive an equation relating the temperature to the velocity of the gas. if nitrogen at 150 °c flows past one section of the tube at a velocity of 2.5 m/s, what its temperature at another section where its velocity is 50 m/s? cp = 7/2 r.

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
