(Solution) - Hydrogen flows through a nozzle exit of diameter 10 cm -(2025 Original AI-Free Solution)

Paper Details

Hydrogen flows through a nozzle exit of diameter 10 cm with an average velocity of 200 m/s. If the mass flow rate of air is measured as 1 kg/s, determine
(a) The density (?) of hydrogen at the exit in kg/m3.
(b) Determine the specific volume (v) of hydrogen at the exit in m3/kg.
(c) If hydrogen is supplied from a tank, determine the loss of mass of this tank (in kg) in one hour.
