Carbon black is produced by the decomposition of methane:
For equilibrium at 923.15 K (650°C) and 1 bar,
(a) What is the gas-phase composition if pure methane enters the reactor, and what fraction of the methane decomposes?
(b) Repeat part (a) if the feed is an equimolar mixture of methane and nitrogen.
The ship must unload 1000 metric tons within 5 hours to avoid demurrage charges. Estimate the power required by the pump. Take the pump efficiency as 70%. Physical properties of toluene: density 874 kg/m3, viscosity 0.62 mNm-2
For the numerical values I = 10 A,N = 500 turns, g = 5 mm, a = 20 mm, b = 2 mm, and l = 40 mm, find the magnitude of the force. Assume infinite permeability of the core and neglect leakage.
A sinusoidal signal, with amplitude of 3.25 volts, is applied to a uniform quantizer of the mid-tread type whose output takes on the values 0, ±1, ±2, ±3 volts. Sketch the waveform of the resulting quantizer output for one complete cycle of the in..
Let the subset of those components given which have strictly positive initial concentrations. Give an algorithm to generate the set of components which are strictly positive for all subsequent (positive) times.
What Z values correspond to scores of 100, 118, and 140?
Design a decanter for this duty, for a feed rate of 3500 kg/h. Concentrate on the separation of the water and aniline. The densities of water-aniline solutions are given in Appendix F, Problem F.8, available in the online material at booksite.Else..
Methanol can be manufactured by the gas phase reaction CO(g) + 2H2(g)?CH3OH(g)at 400K and 1.013 bar.The following data are available;?H298= -90.71 kJ/mol?G298= -24.33 kJ/mol.
Sulfuric acid solution 98% by weight is known to have a specific gravity of 1.84. H2S04 concentration declared 98% of the weight of the a.pound H2S04 per ft ^ 3 solution
For a gas flow rate of 100,000 m3 /h, at the reactor conditions, determine how many cyclones operating in parallel are needed and design a suitable cyclone. Estimate the size distribution of the particles entering the filters.
A value of mass transfer coefficient kg = 0.0150 kg /m2-s . it was also found that the corresponding heat transfer co efficient = hc = 15 j /m2-s
Draw circuit diagrams and show polarity markings.
