- TVA’s Kingston Fossil Plant near Cedarville, Tennessee, burns about 14,000 tons of coal a day. A typical rail car is 53 ft long from coupling to coupling, weighs 30 tons empty and can carry 100 tons of coal. How many minutes would you have to wait at a crossing for this train to pass, each day, if it was pulled by four locomotives, each 70 ft long and moving at 10 miles per hour through town? Such delays cause decreased ability to provide effective emergency response times and interference with commuters and local freight delivery affecting the local economy.In an industrial chemical process, salt solution enters a mixing tank at a rate of 5 kg/s. Industrial water enters the same tank at the rate of 20 kg/s. They are thoroughly mixed together and the diluted solution leaves the tank. If the liquid in the tank is to remain constant, determine the rate of flow of the diluted solution. (Answer in kg/s)SpaceX recently launched their Falcon Heavy rocket (Feb. 6, 2018). It is based on their existing Falcon 9 rocket. The Falcon 9 rocket has a first stage which is a 40 m high by 3.7 m diameter cylinder. This cylinder contains the fuel used to propel the rocket which consists of RP-1 (rocket propellant-1, high grade kerosene), and liquid oxygen, O2 (`). RP-1 is a complex mixture of hydrocarbons but let’s approximate it with a chemical composition of C12H26. The densities of the fuel are ρ (RP − 1) = 0.83 g cm3 ρ (liquid O2) = 1.141 g cm3 If the total volume available for the two tanks is contained in the 40 m high by 3.7 m diameter first stage, determine the volume of each individual tank that will provide the exact amount of RP-1 and oxygen for the reation (no limiting reagent) and take up the entire volume of the first stage. Here are some suggestions to guide you. 1. Write a balanced combustion reaction for C12H26 with O2. 2. Determine the ratio of the volumes of the individual RP-1…

If false,provide an example,illustration,or briefexplanation of why the statement is false. Q.) In a chemical mixing problem involving two tanks,the rate at which fluid moves from tank 1 to tank 2 must be the same as the rate at which fluid moves from tank 2 to tank 1.Urea (H2NCONH2) is used extensively as a nitrogen source in fertilizers. It is produced commercially from the reaction of ammonia and carbon dioxide: 2NH3(g)+CO2(g)----heat----> H2NCONH2(s) + H2O(g) Ammonia gas at 223°C and 90 atm flows into a reactor at a rate of 500 L/min. Carbon dioxide at 223°C and 45 atm flows into the reactor at a rate of 600 L/min. What mass of Urea is produced per minute by this reaction assuming 100% yield.
- A 500 m2 botanical garden which harvest 1000 flowers per day of 15 variations, in a year the average rainfall is 170 cm/yr. With the rainfall 30% percolates into the ground and the rest are harvested in a spherical cistern. 35% of the cistern water is used for watering that percolates into the ground and the rest of water evaporate. Every day they sprinkled water from the cistern and dug wells. Of the dug well water, 75% evaporates and the remainder percolates back into the ground. (Steady State Condition) What is volume of rainfall in the botanical garden? Volume of water in the cistern Volume of water from the well Volume of water that evapotranspiration from the well Total Volume of water that repercolates into the groundA brine solution of salt flows at a constant rate of 4 L/min into a large tank that initially held 5 L of pure water. The solution inside the tank is kept well stirred and flows out of the tank at a rate of 2 L/min. If the concentration of salt in the brine entering the tank is 0.1 kg/L, determine (a) the mass and (b) the concentration of salt in the tank after 30 mins.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…
- Chemistry Cyclohexane (C6H12) can be made by the reaction of benzene (Bz) (C6H6) with hydrogen according to the following reaction: C6H6 + 3H2 → C6H12 For the process shown below, determine the ratio of the recycle stream to the fresh feed stream if the overall conversion of benzene is 95%, and the single-pass conversion is 20%. Assume that 200 mol/h of 30% benzene and 70%H2 is used in the fresh feed, and that the composition of the recycle stream is 22.74 mol % benzene and 77.26 mol % hydrogenStress may trigger some headaches. This could be related to increased (hypertension) or decreased (hypotension) osmotic pressure in cerebrospinal fluid and inside the skull. The human body temperature also may be influenced by these changes. Calculate the pressure p ( in units of torr) inside the brain, if it resulted in 39oC fever. You need to assume a normal body temperature is 37oC, the average CP,m of the human body is approximated as 12.5R, and the outside pressure is 1 atm. Also, assume the process of giving the headache is adiabatic.In a metered-dose inhaler (MDI), such as those used for asthma medication, medicine isdelivered by a compressed-gas propellant. (The device is similar in concept to a can of spraypaint.) When the inhaler is activated, a fixed amount of the medicine suspended in thepropellant is expelled from the mouthpiece and inhaled. In the past, chlorofluorocarbons(CFCs) were used as propellants; however, because of their reactivity with the Earth's ozonelayer, they have been replaced by hydrofluorocarbons (HFCs), which do not react withozone. Now HFC use is also being reduced due to their high global warming potential. In one brand of inhalers, the original CFC propellant was replaced by HFC 227ea (C3HF7,heptafluoropropane). The volume of the inhaler propellant reservoir is 1.00×102 mL, and thepropellant is charged into the reservoir to a gauge pressure of 4.443 atm at 23°C. An onlinesearch for properties of HFC 227ea yields the information that the critical temperature andpressure of the substance…
