In the production of ammonia from hydrogen and nitrogen the conversion, based on either raw material, is limited to 15%. The ammonia produced is condensed from the reactor (converter) product stream and the unreacted material is recycled. If the feed contains 0.2% argon (from the nitrogen separation process), calculate the purge rate required to hold the argon in the recycle stream below 5.0%. Percentages are by volume.
Calculate the volume of lithium hydroxide at 0.12 M. required to neutralize 25 mL of sulphuric acid at 2.5 M. 3 marks 2. A sample of 2.5 g of solid NaOH will neutralize 125 mL of sulphuric acid. Calculate the molarity of the sulphuric acid. 3 mark..
Use the van der Waals, the Soave-Redlich-Kwong, and the Peng-Robinson equations to determine the molar volumes of the saturated phases of ethylene at 260 K (the saturation pressure is 30.35 bar). Compare with the tabulated values,VL = 0.0713 l/m..
Calculate the size of the current pulse applied at 6 ms for 1 ms, necessary to raise Vm to 40 mV.
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.

what is the conversion conversion if both the reactors are operated in series when feed note =20 litre/min , feed concentration = 1 g mol /liter , rate constant
What is the speed of the rotor field at full load (i) with respect to the rotor? and (ii) with respect to the stator?
Your are designing a single flash separation process for a stream that contains 45% n-pentane (the rest is propionaldehyde). The mixture is to be flashed at 35 °C and you must determine the pressure so that the purity of n-pentane is 95%. What is ..
