Question: hydrogen gas is stored in a reservoir at 300 k...

Question details

Hydrogen gas is stored in a reservoir at 300 K and 900 atm. Given that the molecular weight of H2 is W-2.016 g/mol and γ-: 1.4, find the speed of sound in the reservoir (Note: R-Ru/W R,-8.314 J/mol-K). Now consider a round duct attached to the reservoir with a valve. When the valve is opened, an isentropic and adiabatic flow starts in the duct. If the Mach number of the flow in rate? the duct is M -1.5, at a section where the duct diameter is 2mm, what is the mass flow where the universal gas constant 1S
