Explain Non-adiabatic operations of flow reactors. 15In non-adiabatic operations, heat interchange with the surroundings will beaccounted. The conversion can be defined as the ratio of the net heat still needed after heattransfer to raise the feed to T2to the heat released by reaction at T2. Thus,XA= (C'P?T - Q) / (-?Hr2)Where C'Pis the mean specific heat of either unreacted feed stream or of completelyconverted product stream per mole of entering reactant 'A';?T = (T2 - T1); T1& T2are thetemperatures of the entering and leaving streams & 'Q' is the heat interchange to thesurroundings per mole of entering reactant 'A'
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
Calculate the wavelength, in meters of a photon capable of exciting an electron in He+ from the ground state to n = 4
What are some of the obvious and less obvious ethical issues involved in product recalls? How might these ethical issues come into conflict with a particular company's economic concerns?
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.
12. Comparing emitted Auger electrons (AES, Auger electron spectroscopy) with X-rays (EDX / EDS, energy-dispersive X-ray spectroscopy), what is the difference in the analysed sample volume (i.e. volume of the sample from which the signal comes)?
What concentration of phosphorus (P) would you expect at the top of the boule (X=0)? If the boule is 1 m long and has a uniform cross section,at what position (or Xvalue)would you expect the concentration of phosphorus to be twice as large as it is..
The mole fraction of ammonia in exit gas from the tower is 0.003. Assuming isothermal operation and considering the following equilibrium data calculate the height of the packed bed.
A factory is producing tablets. It is required to design a system such that: The bottles moves till it reach the position shown (A) and 50 tablets are dropped in
Write a balanced equation for the neutralization of hydrochloric acid by each of these substances. Which of these substances will neutralize the greatest amount of 0.10 M HCl per gram? Explain how you arrived at the answer.
A preliminary (Class 4) estimate of the ISBL capital cost of building a 200,000 ton per year ethanol plant by corn dry milling has been stated as $130 MM -30%/+50%.
The physical properties of the fluid are: density 875 kg/m3, viscosity 1.46 mN m-2 s. Also, determine the NPSH, at this flow rate, if the vapor pressure of the fluid at the pump suction is 25 kN/m2.
