The output 𝑦(𝑡) of a first-order process is governed by the following differential equation where 𝜏𝑝 is a non-zero time constant, 𝐾𝑝 is the gain and 𝑓(𝑡) is the input with 𝑓(0) = 0. Assume 𝑦(0) = 0. The transfer function for this process is (consider 𝑠 as the independent variable in the Laplace domain)

Sugarcane molasses containing 50% sucrose, 1 % invert sugars, 18% water and 31 % other solids is mixed with corn steep liquor containing 2.5% invert sugars, 50% water and 47.5% other solids to produce a diluted sugar mixture containing 2% invert sugars. 125 kg corn steep liquor and 45 kg molasses are fed into the mixing tank. How much water should be added to the mixing tank to produce the desired diluted sugar mixture?
