Steam velocities of 25 m/s are in general sufficient for most saturated steam applications. Condensate return savings estimator The reduced pressure in the steam space means that a pressure difference exists across the control valve, and steam will flow from the high-pressure zone (upstream of the control valve) to the lower pressure zone (the steam space in the equipment) in some proportion to the pressure difference and, ideally, balancing the rate at which steam is The theoretical steam rate (sometimes referred to as the water rate) for stream turbines can be determined from Keenan and Keyes or Mollier charts following a constant entropy path. For non critical pressure drop the outlet pressure - p o - after the control valve is more than 58% of the inlet pressure - p i - before the control valve. Includes 50+ different calculations.
