It is proposed to cool a stream of 75 mass-% sulfuric acid solution at 333.15 K (60°C) by diluting it with chilled water at 277.15 K (4°C). Determine the amount of water that must be added to 0.45 kg of 75% acid before cooling below 333.15 (60°C) actually occurs
A mixture of acetone and isopropanol containing 50 mol% acetone is to be distilled continuously to produce an overhead product containing 80 mol% acetone and a bottoms containing 25 mol% acetone. If a saturated-liquid feed is employed, if the colu..
Zirconium is one of the few metals that retains its structural integrity upon exposure to radiation. The fuel rods in most nuclear reactors therefore are often made of zirconium.
If the stress at the center is 12,000 psi, what is the strain? Also, calculate the unit volume change e and the strain-energy density u at the center.
Determine the standard heats of Reactions. Discuss the purpose of feeding oxygen to the reactor. Assuming no heat is lost to the surroundings, estimate the temperature of the gas and slag leaving the gasifier.
What is the confidence interval for probability levels of 0.95 and 0.99?
A solution of nitric acid has a specific gravity = 1.502. Stating that the concentration of nitric acida. molarity
The feed (CAo= 1.0, CRo= 0, CSo= 0) enters two mixed reactors in series (?1= 2.5 min,?2= 10 min) knowing the composition in the first reactor (CA1= 0.4, CR1= 0.4, CS1= 0.2),find the composition leaving the second reactor (using fractional yield co..
