Sonic choked flow
WebChoked flow usually happens when there is a high pressure drop across the valve. Choked flow begins when a pressure ratio is reached (1.8 for methane) and the gas velocity is at … WebQuestion: One of the most important areas of study in energy, thermodynamics and mechanical engineering is choked flow, which is unique in its behavior. Lack of knowledge regarding choked flow is a handicap for ME's with the result being that many engineering problems remain unsolved, especially those problems associated with the flow of air.

Do you want to know the maximum physical possible amount of steam that can pass through a 1" OD pipe (are you referring to 3/4" NPS)? If so, the maximum flow is limited by the choked (sonic) flow condition. The mass flow rate at the choked condition is given by: = where:
WebDetermination of Choked Nozzle Flows A common flow problem is to determine the exit conditions and losses of a given choked nozzle with prescribed reservoir stagnation conditions pr, hr, and a prescribed exit pressure pe. We first note that the mass flow in this situation is known, and given by combining relation (2) with the fact that A∗ =A WebWhen the gas velocity is choked, the equation for the mass flow rate is: or. Where the ratio of the absolute source pressure to the absolute downstream ambient pressure is less than [ ( k + 1 ) / 2 ] k / ( k - 1 ) , then the gas velocity is non-choked (i.e., sub-sonic) and the equation for the mass flow rate is: or
