For the series reaction Ak1Rk2S, it is observed that the first step follows a first orderkinetics while second step follows a zero order kinetics. If this reaction takes place in a batchreactor with CRo= CSo=0,showthattR,max= (1/k1) ln [(k1CAo)/k2] and alsoCR,max/CAo= 1 - [k2/(k1CAo)] {1 - ln [k2/(k1CAo)]}. Where 'k1' and 'k2' are rate constants,tR,maxis the time at which the maximum concentration of 'R' is obtain and CR,maxis themaximum concentration of 'R'
In terms of heat treatment and the development of microstructure, what are two major limitations of the iron-iron carbide phase diagram?
Determine the values of the constants a and c and state the units and draw the path on a PV diagram also draw Path on the diagram and calculate the heat and work interchanges between the system and surroundings.
Consider 1 mole of ideal gas at 1 bar and 300 K, which of the following statements is true? The absolute entropy of the system is negative. Helium (m=4 amu) will have a larger entropy than argon (m=40 amu).
A continuous filter is used to separate a clear filtrate from alumina particles in a slurry. The slurry has 30% by weight of alumina (specific gravity of alumina = 4.5). The cake retains 5% by weight of water. For a feed stream of 1000 kg/hr, determi..
A 100-liter fed-batch fermenter was successfully operated for 200 h using an aeration rate of 14 l/s and a 5 W agitator. It is proposed to scale the fermentation up to 10,000 liters. What agitator power consumption is required?
Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, fol..
Suppose that R2 is decreased to 0.5 min/ft2. Compare the old and new values of the ultimate gain and the critical frequency. Would you expect the control system performance to become better or worse, justify your answer.
Dependence of measured energy on temperature for a pyrometer - Plot the volumetric flow rate vs. height
Which of the following would you expect to be elastomers and which thermosetting polymers at room temperature? Justify each choice.
Prepare a piping diagram and calculate the pipe size as well as the required power of the pump. You need to specify the type of fittings and the pipe material for your calculations.
The estimated cost of the pipes, per unit length is: schedule 40 carbon steel $5, schedule 80 carbon steel $8.30, stainless steel (304) schedule 40 $24.80. Installation and fittings for all the materials adds $16.5 per unit length. The downtime re..
