CA,OUT (milli mol/l). 16 30 5 60. The reactor volume is 0.1 liter and the feed concentration at the temperature of the reactor is Cac =100 milli mol/l. Find the rate equation which satisfactorily represents the cracking reaction. in the above problem if we ignore density changes, what is the rate equation represents the reaction.

An evaporator is used to concentrate 12 000 kg/h of a 15% solution of NaOH entering at 60oC to a product of 50% solid. The pressure of the saturated steam used is 300 kPa and the pressure in the vapour space of the evaporator is 11.7 kPa. The overall heat transfer coefficient is 1 560 W/m2K. Calculate the steam used and the steam economy in kg vaporised/kg steam.
Brackish water is desalinated by evaporation for irrigation purposes. If the feed water has 800.96 ppm of salt, and if the product has to contain 0.0034 % salts as illustrated in Fig 1, what fraction of the feed water should bypass the evaporator?
Find the volume of the solid obtained by rotating the region bounded by the curves y=cos(x), y=0, x=0, and x=π/2 about the line y=1.
Use the Shell Method to compute the volume of the solids obtained by rotating the region enclosed by the graphs of the functions y=x^2 , y=8−x^2 and to the right of x=0.5 about the y-axis.
Find the volume of the solid obtained by rotating the region bounded by y=x and y=x^1/2 about the line x=5.
In a heat exchanger shown in Figure 3, the cold water stream receives 10,382 kcal/h of heat from the hot water stream(pink color). At the inlet (Point 1), the cold stream is at a temperature of 29oC and Psat. The outlet (Point 2) of the cold stream is 700 cm below the inlet. You can assume that there were no other heat losses due to friction. If the volumetric flow rate of the cold water stream is 825 L/hr, calculate the specific enthalpy(KJ/kg) of the cold-water stream at Point 2.
Input the final answer(value only) correct to 2 decimal places.
Take the density of the cold-water stream as 998 Kg/m3

In past research studies, the proposed reaction has been run in the vapour phase
with reactor temperature of 240-300 oC, total pressures of 2-30 atm, and
hydrogen to benzothiophene feed ratio of 4:1 to 9:1. These experiments resulted
in the following reaction rate equation:
