A current i(t) = 20 cos(2π × 60)t A flows through a wire. Find the charge flowing, and the number of electrons per second that are passing some point in the wire.
Terephthalic Acid. (TPA) is produced by the reaction of p-Xylene. ,(PX) and Oxygen in the presence of a catalyst and solvent (S): Process conditions are provided for the Air entering the reactor and the reactor off gas.
Write a differential mole balance on phosphoric acid and provide an initial condition. [Start by defining np (k mol) to be the total quantity of phosphoric acid in the tank at any time.]
A solution of the two components that contains 62% mol toluene is slowly heated at constant pressure. When the solution begins to boil the temperature reads 120 °C. What is the pressure?
A spherical ball of benzoic acid (diameter = 1.5 cm) is submerged in a pool of still water. The solubility and diffusivity of benzoic acid in water are 0.03 kmol/m3 and 1.25 x 10-9 m2/srespectively.
The geometry and dimensions for a section of the blood vessel are shown on the right. Based on the Poiseuille's law the viscous resistance against blood flow through this section is determined to be 0.0002 mmHg•s/ml. If the diameter of the vessel ..

Propane in the feed to the unit and 80% of the pentane fed to the unit. The mole fraction of butane in the distillate is yB ? 0.4 . The bottom stream contains all of the hexane fed to the unit. Calculate the distillate and bottoms streams flow rate a..
HEAT TRANSFER PROBLEM NO18 - The configuration of a furnace can be approximate as an equilibrium triangular duct which is usually long enough so that the end effects are negligible , the hot wall is maintained at 900 k and has an emissivity e1 = 0..
Discuss the criteria that you would use to determine the required dimentions of this device. What are the potential failure mechanisms? What materials might be appropriate for the manufacture of this device, and why?
The effect of a hazardous substance depends on the concentration of the substance that is present in the body's systems. The concentration depends on the stages of toxicokinetics What are the four main stages of toxicokinetics
The heat capacity at constant pressure of hydrogen cyanide is given by the expression Cp[J/(mol ·°C)] = 35.3 + 0.0291T(°C) (a) Write an expression for the heat capacity at constant volume for HCN, assuming ideal gas behavior.
For the design of internal-pressure cylindrical vessels, the API-ASME Code for Unified Pressure Vessels recommends the following equations for determining the minimum wall thickness when extreme operating pressures are not involved:
