    Q1. Starting with a pulp with a water content of 99%, how much water must be removed to obtain one ton of paper containing 60% water?

    Solution.
    Water removed

    Pulp 1-ton paper
    99 % H20 60% H20

    Basis: 100 ton of paper

    Let x represent the pulp used to produce paper
    Let y represent the paper created by the pulp.
    Let w represent the water removed by the evaporator.

    X = W +Y
    (99/100) X = W(0) + 1(60/100)
    X = 0.60

    Substitute into equation to calculate the amount of water removed.

    0.60 = W + 1
    0.40 = W
