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.
Determine the maximum layer of the hydrogel membrane that would result in an oxygen concentration of at least 1.104 mol/mL everywhere in the capsule.
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production. The particles ionize molecules in the air,
List the formulas of three soluble bromide salts and three insoluble bromide salts. Do the same exercise for sulfate salts, hydroxide salts, and phosphate salts (list three soluble salts and three insoluble salts).
Develop project plans for the design and construction of the following processes. Use Figure 1.2 as a guide to the activities that must occur. Estimate the overall time required from launching the project to the start of operation.
A 2014 Toyota Prius has a drag coefficient of Cd at road speed, using A m2 as the reference area. Determine the horsepower required to overcome drag at a velocity of v m/s. Calculate the answer if Cd= 0.26; A= 2.33m2 and v=30 m/s. Compare this fig..
In Uniformly varying load in simply supported beam, when we are calculating reaction at support we say centorid of triangle will be at 2x/3 from a to b. but, when calculating moment we say centroid will lies at x/3 from a to b, why?
Why does the dielectric constant of water drop as a function of temperature?
Lowest standard deviation of measurements, As the Quality Control Manager of a chemical company, you are asked to decide between several process methods that are supposed to uniformly mix 37.4 milligrams into a chemical solution.
How many kilograms of natural gas are flowing through the pipelines per hour ( use different steps required in material balance calculations).
You are presented with patient X who has a genetic disease. You discover a mutation inall aquaporin2 (AQP2) channels manufactured in the epithelial cells of the collecting ductso that there is no increase in water permeability when the mutated cha..
describe the principles of a vapour adsorption refrigeration system and compare this to a vapour recompression system.
1. It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a p..
