release of O2 gas

Thanks Curioso77. While using Bernoulli's equation for Gravitational head mgh_in will get canceled with mgh_out. Under kinetic head, 1/2mv^2, m will be equal in and out. v_out will be 1 mach as max speed that can be attained by a shock wave. speed v_in should we assume equal to what? Under...

Thanks Q_Goest. Relationship between P and T is not explicitly given there. Can you help me in deriving such an equation? Vishwajeet

ideal gas equation pV = nRT = n^2 k_B T. Therefore, variation of pressure and square of mole quantity should decrease so that your suggestions stands true. Please go ahead to discuss any further clarification for my help. Thanks for quick response Tobychev.

Dear Friends, I carried out an experiment of sudden release of oxygen (open nozzle) from an oxygen cylinder used for medical college and hospitals. I found that pressure drops quite rapidly and cylinder surface cools from outside such that water droplets accumulate on its surface. This...
