Problem 1: A closed tank, 1 m3 in volume is filled with water at 1 bar 80 °C. A second identical tank contains 20 kg of steam at 20 bar.
a) What is the mass of water in tank 1? b) What is the temperature and phase in tank 2? c) The contents of the two tanks are mixed together in a third closed tank whose volume is 2 m3. Heat is added or removed, as needed, to bring the final temperature to 175 °C. What is the final pressure?
Write an equation for the combustion of PVC in oxygen. Suggest a reason why its incineration poses a serious risk during a fire.
Aniline is produced by the hydrogenation of nitrobenzene. The reaction takes place in a fluidized bed reactor operating at 270 °C and 20 bar. The excess heat of reaction is removed by a heat transfer fluid passing through tubes in the fluidized be..
If the container holds 1.3 kg of dry air, what are the final specific and relative humidities of the air in the container? what is the dew point?
Algae grown in water containing some 18O (in H2 18O) evolve oxygen gas with the same isotopic composition as the oxygen in the water. When algae growing in water containing only 16O were furnished carbon dioxide containing 18O, no 18O was found to..
For the consecutive reaction , A----K1(B-K2--(C, numerical values are K1 = 0.85 hr^-1, K2 = 0.13 hr^-1, Cao = 64 kg -mole /m3 and Cbo = Cco =0 . what is the maximum concentration attained by B when as 1).Batch reactor ,( 2 ) -single stage continuo..
1. hydrochloric acid solution with a specific gravity = 1.12. stated that the concentration of hydrochloric acida. molarityb. % By weight per volume
If the temperature of the contents is increased by 10 C degrees, the reading on the Kelvin thermometer should increase by 273 K
It has been suggested that carbon dioxide can be recovered from flue by using a membrane process. The flue gas has the following composition:
Assuming that the two unsealed faces of the wood immediately jump to an equilibrium moisture content of 10 lb H20 per 100 lb of dry wood, determine the time for the moisture to penetrate to the center of the slab (2 in. from either face). Assume a..
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..
Determine the number of theoretical plates required to reduce to hydrocarbon content of 0.05 mole % assuming the oil is non-volatile.
When heavy oils are cracked in a catalytic or thermal cracking process, lighter hydrocarbon compounds are formed. Most cracking processes on heavy oil feeds form products with carbon numbers ranging from two to greater than twenty.
