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?
The flow rate Q3 and enthalpy H3 of the steam after pressure and temperature reduction are respectively Q1 and H1 before the reduction; the enthalpies of the water used for cooling are Q2 and H2. It holds that Q1 + Q2 = Q3, and Q1H1 + Q2H2 = Q3H3
