To prepare a delicious banana milk on an industrial scale, there is an experimental process that consists of seven unit operations.A stream of banana (whose components are fruit, peel, and moisture) is fed to a peeler, where 99.9% of the peel is removed.This stream should become pulp, so it is mixed with an additive Q to avoid pulp oxidation. This mixture is then sent to anextruder press wherein a stream of a 50:50 mixture of additives Q and R is added. The resulting flow of 30 kg/h has acomposition of 2% additive R and 5% additive Q.This flow is then fed to an agitated mixer. To the same mixer is fed a dairy stream of 250 kg/h that contains 70% milk (therest is water) and a sweet aqueous stream that contains 30% sugar. For each 25 kg/h of dairy flow, 2 kg/h of the sweet flowis fed.The stream that leaves the agitated mixer has 5% fruit and 0.005% peel and enters a series of two thermal processes in whicheach operation allows 5% of the water and 2% of the milk to evaporate. The resulting flow of the heat treatment (hot bananamilk) finally joins another mixer, where the flavoring G is added. The final banana milk contains 30% water.1. Draw a complete diagram of the process. Label all streams properly.2. Calculate:a. the composition (in %) and flow (kg/h) of the initial stream of bananas;b. the annual flow of peels (in ton/yr) that are separated in the process, assuming 300 days of 24/7 operation;c. the mass lost (in kg/h) during the thermal process; andd. the composition (in %) and flow (kg/h) of the final product stream.3. In the case where the density of the final product is 1.3 g/mL, calculate how many 0.2 L packages of banana milk areproduced per month, assuming 30 days of 24/7 operation.

The seven-unit operations given for the production of banana milk are: 1) Peeler 2) Mixer 3)…

3.A core sample is saturated with an oil (po = 35°API), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (pw = 1 g/cm'), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm' water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.
In biological systems, enzymes are used to accelerate the rates of certain biological reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 μg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 μg mol/(mL)(min). Determine the production rate of glucose for this system in units of lb mol/(ft3)(day). A. 0.0015 lb mol/(ft3)(day) B. 0.0315 lb mol/(ft3)(day) C. 0.0539 lb mol/(ft3)(day) D. 0.3569 lb mol/(ft3)(day)

Grammer Chicken produces canned chicken a la king. The chicken a la king passes through three departments: (1) Mixing, (2) Retort (sterilization), and (3) Packing. In the Mixing Department, chicken and cream are added at the beginning of the process, the mixture is partly cooked, and chopped green peppers and mushrooms are added at the end of the process. Conversion costs are incurred evenly throughout the mixing process. November data from the Mixing Department as follows: 1 Summarize the flow of physical units and compute the equivalent units. (Hint: Each direct material added at a different point in the production process requires its own equivalent-unit computation.) i. Check your spelling carefully and do not abbreviate. ii. Follow the format of the exhibit that shows the flow of physical units and output in terms of equivalent units. iii. Complete all input areas. Be sure to include any zero balances in the report. 2 Compute the cost per equivalent unit for…

Lactic acid is an important pharmaceutical product that is manufactured by fermentation of glucose. To separate the lactic acid from the biomass, filtration followed by centrifugation is employed. A mix containing 23% by mass lactic acid enters the filtration unit at the rate of 6,456 kg/hour. After filtration, the sludge of lactic acid/biomass contains 12 % by mass lactic acid and the filtrate itself contains 100% lactic acid by mass. The sludge then goes to the centrifuge where the solids generated contain 8% lactic acid by mass and the liquid portion stream has 100% lactic acid by mass. Calculate mass flow rate in kg/hour of the stream leaving the filtration unit containing pure lactic acid. [report number with one decimal e.g. 100.4]
