How to simulate a steam-water heat exchanger using a simple heat exchanger in order to calculate the steam consumption

Note: 0.5MPa saturated steam is used to heat 1.0MPa hot water from 80°C to 95°C; how can the steam consumption be calculated through simulation? Cold side: water, pressure 1.0 MPA, flow rate 100 t/h, heated from 80°C to 95°C. Hot side: 0.5 MPa saturated steam, converted into condensed water through heat exchange. Calculation parameter: steam flow rate. I mainly want to learn how to use PROII for simulation calculations; could someone please send me the *.prz file related to these simulations? Thank you!
It’s simply a heat balance equation: the heat required by water is equal to the heat released during the saturated condensation of steam. This can be calculated using a heat exchanger model, or it can also be done manually. Rough estimate: 100*1000*（95-80）*1/500 kg/h of steam
It can be calculated by hand, but there are quite a few similar projects; it’s like learning a bit of it and using software for the calculations.
