How much water is needed to convert low-pressure superheated steam into 0.4 MPa steam using a temperature and pressure reducing device? What is the amount of steam produced in the end, and how is this calculated?

How much water is required for low-pressure superheated steam to be converted into 0.4 MPa steam using a temperature and pressure reducer? What amount of steam will be produced in the end? How can this be calculated? Is there a specific formula for it?
It is necessary to know the initial pressure and temperature of the low-pressure steam; this can be determined through simulation software, or by calculating using the steam enthalpy values
Specific data is required for simulation calculations
If you know how to use the ASPEN software, it’s very easy.
There seems to be a calculation included in the standards for temperature and pressure reducers
If I remember correctly, the temperature and pressure reducer first reduces the pressure through diffusion, and then adds water to lower the temperature; the pressure is reduced to 0.4, at which point the superheated saturated steam plus water turns into saturated steam at its corresponding pressure
