In the manufacture of aniline, liquid nitrobenzene at 20 ŽC is fed to a vaporiser where it is vaporised in a stream of hydrogen. The hydrogen stream is at 30 ŽC, and the vaporiser operates at 20 bar. For feed-rates of 2500 kg/h nitrobenzene and 366 kg/h hydrogen, estimate the heat input required. The nitrobenzene vapour is not superheated
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..
An LiClIfiO solution at 298.15 K (25°C) is made by adiabatically mixing cool water at 283.15 K (10°C) with a 20-mol-% LiC1/H20 solution at 298.15 K (25°C). What is the composition of the solution formed?
The value for the diffusivity of water vapor in air is 0.22 cm2/s at 0°C and 1 atm. The mass velocity of air is taken relative to the pipe wall.
What is the probability that k columns in a random k x n binary matrix have rank k? How about the probability that k + 1 columns in this matrix have rank? Compute these two probabilities for n = 16 and k = 5.
Assuming that there is plenty of cooling water available at 273.15 K (O°C), what is the maximum temperature level at which heat in the amount of 2000 kJ can be made available for each kilogram of steam flowing through the process?
All that is required is a four-stage counter which, having counted from 0000 to 1001 (i.e., decimal 0 to 9; ten states), resets to 0000 on the next clock pulse. Develop a block diagram of an asynchronous decade counter and show its timing diagram.
A vapor of titanium isopropoxide (partial pressure = 133 pascal) is reacted in O2 rich CH4 flame at T=2000K. Calculate the diameter of the nuclei.
Write the balanced formula, complete ionic, and net ionic equations for the reactions that occur when the following are mixed. a. potassium hydroxide (aqueous) and nitric acid
10g of steam at l00°C and a pressure of one atmosphere condensing into water at the same temperature and pressure. (The latent heat of vaporization of water is 22571 Jg^-1).

An experiment was performed to determine the effect of four different chemicals on the strength of a fabric. These chemicals are used as part of the permanent press finishing process. Five fabric samples were selected, and a randomized complete block..
What is the magnitude of the signal, in volts, that you could expect from the microphone? Assume that we get a maximum signal when the flux varies from 0 to the value of Φ calculated in Part B. (Assume that sound has a frequency of order 500Hz.)Volta..
