Interpretation:
The level response of the tank as a function of time is to be plotted if the drain is closed suddenly and the inflow is constant for 3 min.
Concept introduction:
For chemical processes, dynamic models consisting ordinary differential equations are derived through unsteady-state conservation laws. These laws generally include mass and energy balances.
The process models generally include algebraic relationships which commence from

- Chemical Engineering Questionarrow_forwardA steam boiler or steam generator is a device used to produce steam by transferring heat to water. In our case, the combustion chamber is fueled with propane (C3H8) at a flowrate of 50.0 mol/h in an excess air of 50%. Assume that both propane and air are fed at 25ºC and the combustion gases leave the chamber at 200ºC. Pressure can be assumed to be atmospheric.* Determine: 1. The heat obtained assuming complete combustion. Compare the results using elements or compounds 2. The steam flowrate that could be generated if the heat is directed to obtain superheated steam at 2 bar and 160ºC from saturated liquid water at this pressure solvearrow_forwardIn a surface coating operation, a polymer (plastic) dissolved in liquid acetone is sprayed on a solid surface and a stream of hot air is then blown over the surface, vaporizing the acetone and leaving a residual polymer film of uniform thickness. Because environmental standards do not allow discharg- ing acetone into the atmosphere, a proposal to incinerate the stream is to be evaluated. The proposed process uses two parallel columns containing beds of solid particles. The air– acetone stream, which contains acetone and oxygen in stoichiometric proportion, enters one of the beds at 1500 mm Hg absolute at a rate of 1410 standard cubic meters per minute. The particles in the bed have been preheated and transfer heat to the gas. The mixture ignites when its temperature reaches 562 C, and combustion takes place rapidly and adiabatically. The combustion products then pass through and heat the particles in the second bed, cooling down to 350 C in the process. Period- ically the flow is…arrow_forward
- Propane is burned completely with excess oxygen. The product gas contains 24.5 mole% CO2, 6.10% CO, 40.8% H2O, and 28.6% O2. (a) Calculate the percentage excess O2 fed to the furnace. (b) A student wrote the stoichiometric equation of the combustion of propane to form CO2 and CO as: 2C3H8 + 11O2 → 3CO2 + 3CO + 8H2O According to this equation, CO2 and CO should be in a ratio of 1/1 in the reaction products, but in the product gas of Part (a) they are in a ratio of 24.8/6.12. Is that result possible? (Hint: Yes.) Explain howarrow_forwardEnumerate the various methods for catalyst preparation and discuss vividly any one of the methodsarrow_forward2.
