Homework Statement



Total temperature of mixture= 600 K, mass fraction of vapour to mass of total mixture=0.01

Homework Equations



Ideal gas law, Mach area relations, Rankine-hugoniot equations

The Attempt at a Solution


Applied Clausis-Clapeyron relation to find vapour pressure, Then found total pressure via humidity relation that I found from a research paper, Then found temperature from ideal gas law. Using total temperature and this temperature, from the isentropic flow table, found the area ratio.

Is this approach right? or is does it just have to do with assuming a value of static temperature below stagnation temp and proceeding with isentropic relations?

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
