From T$2$ Laboratory explosion incident

Calculate the velocity and mass flow rate of the hydrogen gas released from the reactor

when the rupture disc opened. Start your calculations using a pipe diameter of $1$ inch and a

pipe length of $40ft.$ Also assume the pipe is commercial steel.

Calculate the maximum mass flow rate of hydrogen gas released to the environment and

the mass flow rate flowrate and velocity of hydrogen gas assuming an adiabatic pipe.

Calculate the mass flow rate and velocity of hydrogen gas assuming an isothermal pipe.

Justify any additional assumptions.
