A hydrogen stream is transported through a $2$ in diameter, schedule $80,$ commercial steel pipe to an ammonia reactor. It must enter the reactor at $30$ atm and $20\backslash$deg C $.$ If the total length of the pipe is $300$ m $.$ A$)$ determine the flow rate in kg$/$sec$.$ B$)$ determine the power of the compressor to be installed, knowing that the storage location is at $20$ atm and $20\backslash$deg C$.$
