- If 35,000 kg of whole milk containing 4% fat is to be separated in a 6-hour period into skim milk with 0.45% fat and cream with 45% fat, what are the mass flow rates of the two output streams from a continuous centrifuge which accomplishes this separation? (Ans; Cream=464.8335kg/h, Skim milk= 5368.4998kg/h)You are absolutely the BEST. Finally someone that dosen't calculate this exercise as 836f66dgsffjgvkik!!!! I understand everything you did, but I have one question. Some experts says that km can be calculated by saying Vmax from date divided by 2 and then they find Km by going down on x-axis on the graph. But, you used the MM equation, to solve for Km. Is both method the same? Or is one of them more precise than the other? *And if theres no need to reply back after you answering my question, then I will thank you again for your help. I have more these types of exam questions that I will probably upload later, and I hope someone like you will look at it.1. Estimate the density of a 25-API gravity dead oil at 100 F.

The emission control system has a capitalcost of $815 per kW and reduces SOX emissions by 98% to 0.0918 kg/MWh. Assume thelifetime of the emission control system is 20 years and the power plant produces 650GWh/y. a)What is the annualized cost of this system in dollars per year if the discount rate (interestrate) is 7.0 percent/year? What if the discount rate is 4.0 percent/year? b)What is the cost per 1.0399 x 104 kWh of electricity usage (the average annual U.S.residential electricity consumption in 2017 according to the EIA) at each of the discountrates specified in part a? c)What is the cost per metric ton of SOx removed at each of the discount rates specified inpart a? 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.

- Cereal is being dried in a vertical drier by air flowing countercurrent to the cereal. To prevent breakage of the cereal flakes, some of the exit air from the drier is recycled back to mix with the the moist fresh air. For each 1000 kg/hr of wet cereal fed to the drier, calculate the input of moist fresh air in kg/hr and recycle rate in kg/hr. The available data on stream compositions is (fractions): For water: Fresh air: 0.0132 Wet cereal: 0.200 Exit air: 0.263 Dried Cereal: 0.050 Air entering Dryer: 0.066Medicare does not cover the cost of this prescription medicine, which currently averages $297.78 per kilogram.
