A completely enclosed stirred-tank heating process is used to beat an incoming stream whose flow rate varies. The heating rate from this coil and the volume are both constant.
(a) Develop a mathematical model (differential and algebraic equations) that describes the exit temperature if heat losses to the ambient occur and if the ambient temperature (Ta) and the incoming stream's temperature (Ti) both can vary
(b) Discuss qualitatively what you expect to happen as T and w increase (or decrease). Justify by reference to your model.Notes:? and C? are constants.
A nutritional Calorie is equal to 1000 calories (thermochemical calories), which is equal to 4.184 kJ. How many 8-in-high steps must a 180-lb man climb to expend the 400 Cal from the piece of cake? See Exercise 20 for the formula for potential ene..
The catalyst is in the form of 1/16th inch (1.588 mm) beads with average bulk density of 700 kg/m3 . Design, size, and cost a reactor for making 200,000 metric tons per year of cyclohexane using this process.
Carolina (H2C=CHCHO) is made by selective oxidation of propylene at 2 bar, 350 °C using a molybdenum, iron, and bismuth catalyst on a silica support
Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work are required to compress a gas. At the same time, the gas releases 23 J of heat
Finding the Heat of Reaction (Enthalpy) from Heats of Formation
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2 s.
A 100.0-L aliquot (portion) of this solution is diluted to a final volume of 100.0 mL. Calculate the concentration of the final solution in terms of molarity.
A mixture containing 98 mol% methanol and 2 mol% of an inert contaminant is available as a feed to a formaldehyde plant. The fresh feed to a process consists of 1000 kmol/h of this mixture along with 200 kmol/h of oxygen. All of the oxygen is consume..
The precipitate was collected, dried, and found to weigh 1.36 g. Determine the atomic mass of M, and identify M.
One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light.
