A cleaning solution for a CIP in a heat exchanger for food production is made up by combining one part phosphoric/ glycolic acid concentrate with eight parts of water. a)food technician has 10 liters of the cleaning solution already prepared and needs to increase this to 25 liters. a. How many liters of acid concentrate and how many liters of water should be added to the existing 10 liters of cleaning solution to obtain 25 liters at the correct dilution? b)The acid concentrate is a 10% solution (ie, it is 90% water, 10% acid). What is the concentration of the diluted solution?

I need a labeled process flow chart and a DOF analysis for this problem:  One way to make coal “cleaner” is to gasify the coal into “city gas”. In a proposed molten-iron coal gasification process pulverized coal of up to 3 mm size is blown into a molten iron bath and oxygen and steam are blown in from the bottom of the vessel. Materials such as lime for settling the slag, or steam for batch cooling and hydrogen generation can be injected at the same time. The sulfur in the coal reacts with lime to form calcium sulfide, which dissolves into the slag. The process operates at atmospheric pressure and 1400 to 1500°C. Under these conditions, coal volatiles escape immediately and are cracked. The carbon conversion rate is said to be above 98% and the gas is typically 65 to 70% CO, 25 to 35% hydrogen, and less than 2% carbon dioxide. Sulfur content of the gas is less than 20 ppm. Assume that the product gas is 68% Co, 30% H2, and 2% CO2. Calculate the enthalpy change that occurs on the…

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A chunk of titanium weighing 19.39 grams and originally at 97.14 °C is dropped into an insulated cup containing 80.82 grams of water at 23.76 °C. Water Thermometer Metal- sample 2003 Thomson-Brooks/Cole Stirring rod The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.81 J/°C. Using the accepted value for the specific heat of titanium (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings. Tfinal = °℃

A fully charged battery contains 0.02 kmol Ag₂O (silver oxide) and 0.02 kmol Zn (zinc). The battery is initially at a temperature of 21°C. The fully charged battery is then discharged for half an hour under adiabatic conditions (no heat leaves the system). During the half hour of being discharged, the electric current from the battery does 200 kJ of work external to the battery system (none of this external work heats the battery). During this half hour, 0.001 kmol of both reactants are consumed in the net cell discharge reaction: Please see the following table for heat capacities and heats of formation. The heats of formation below show the amount of energy (kJ) needed to form one kmole of each component. If the heat of formation is negative, then forming that species releases energy (to do work or provide heat). Therefore, to create one kmole of silver oxide 29000 kJ energy is released and is generated in the battery (for work or heat), and if one kmole of silver oxide decomposes…

6. A 15.0 gram sample of silver metal is heated to 96.7∞C and then dropped into 55.0 grams of water at 23.0∞C.      Assuming that all the heat lost by the silver is absorbed by the water, calculate the final temperature of the silver     and water

A countercurrent tunnel dryer is used to dry apple slices from an initial moisture content of 65% to 5% (wet basis). Hot air enters at 95 ° C with 1% RH, and exits at 52.0 ° C. If the product temperature along the dryer is 20 ° C and the solid specific heat of the product is 2.2 kJ / (kg ° C), determine the rate of hot air required to dry the wet product at a rate of 200 kg / hr. Determine the RH of the dryer exhaust air. a. Drying air rate (ma) = kg / hr. b. RH of dryer exhaust air =%

Estimate the dimensions of a drying chamber for a spray dryer that has an output of 1000 kg/h of a heat-sensitive biological material at 60oC containing 5% moisture and having a mean particle size of 100 micrometers. The feed contains 40% solids by weight in an aqueous solution at 4oC. The inlet air has a humidity of 0.01 kg/kg dry air and is at 150oC, while the outlet air is at 80oC.
