I am bothered by the fact that they are not sharing information on how much their new coal gasification plant is producing. However, we may be able to figure it out ourselves. I observed that the gas $($with a molecular weight of $13k\frac{g}{k}$mol, a viscosity of ${10}^{-5}k\frac{g}{m}s,$ and a $k=\frac{c_p}{c_v}=1\mathrm{.}36)$ produced by the plant is transported to nearby industrial consumers using a $15-cm$ inner diameter pipe that is $100m$ long. The pressure gauge on one end of the pipe recorded a reading of $1$MPa absolute$,$ while the other end showed $500$kPa. Although the pipe was hot to the touch and caused me discomfort, my saliva did not evaporate when I spat on it$,$ leading me to conclude that the temperature inside the pipe is $87C.$ Can you help me estimate the flow rate of coal gas through the pipe in both tons per day and cubic meters per second, measured at $1$atm and $0C?$
