The final step in the production of paper involves forming the paper into sheets. This is done in the machine room. The feedstock to the machine room is a high consistency stream, which is 85% cellulose fiber and 15% water. This stream is diluted until it is 95% water and 5% fiber. This slurry forms a sheet on a traveling screen. A large amount of water drains through the screen and is recycled back to the dilution tank. The sheet leaving the screens is about 27% fiber and 73% water. The sheet now travels through press rolls. As the name suggests, these rolls squeeze more water out of the sheet. This water is not recycled. The press rolls increase the fiber content to 48%. The stream leaving the press rolls enters a dryer. In the dryer, water is evaporated and the final product leaving the dryer is 89% water and 11% fiber. A makeup stream is necessary to replenish the water that is lost from the press rolls and through evaporation. Assuming that the mass of the final product leaving the dryer is 1000 kg, calculate the following: a) The mass of the recycle stream b) The mass of the make up stream The final step in the production of paper involves forming the paper into sheets.
