I have generated a hydrological model using the normal method i.e manually. but is it possible to transfer precipitation or evapotranspiration to excel after calibration to predict future precipitation/evapotranspiration.

William,
If your precipitation data comes from the catchment delineation mode, it will most likely appear as a spreadsheet file under the ClimateData folder within your WEAP model folder in Windows. Otherwise, you can go to precipitation in the Data Tree or results and click on the Export to Excel button in the lower right to the right of where the chart is displayed (you may have to navigate to one of your scenarios and not current accounts). However, I usually recommend to simply use the CMIP6 projected precipitation data included in the catchment delineation mode I described in your other post: https://www.weap21.org/index.asp?action=9&read=4600&fID=30
For evapotranspiration, you'll need to navigate to the results and export it to Excel from there. But, normally, future evapotranspiration would be calculated by keeping the same Soil Moisture hydrology parameters, but using the future climate inputs and any expected future land use inputs.
