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:

Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent … See more If the fluid is a liquid, a different type of limiting condition (also known as choked flow) occurs when the venturi effect acting on the liquid flow through the restriction causes a decrease of the liquid pressure beyond the … See more The minimum pressure ratios required for choked conditions to occur (when some typical industrial gases are flowing) are presented in Table 1. The ratios were obtained using the … See more The flow through a venturi nozzle achieves a much lower nozzle pressure than downstream pressure. Therefore, the pressure ratio is the comparison between the upstream and … See more Figure 1a shows the flow through the nozzle when it is completely subsonic (i.e. the nozzle is not choked). The flow in the chamber accelerates as it converges toward the throat, … See more All gases flow from higher pressure to lower pressure. Choked flow can occur at the change of the cross section in a de Laval nozzle or through an orifice plate. The choked velocity is … See more If the upstream conditions are such that the gas cannot be treated as ideal, there is no closed form equation for evaluating the choked mass flow. Instead, the gas expansion should be calculated by reference to real gas property tables, where the expansion … See more The flow of real gases through thin-plate orifices never becomes fully choked. The mass flow rate through the orifice continues to … See more WebAutomation and control products like contactors, HMIs and PLCs handle most of the operating functions of a machine, system or process. Automated applications rely on a variety of controllers, relays, sensors, timers and modules to start, maintain, adjust and stop machinery and other components.
