Calculate the explicit solution of the kinetic differential equation of the reaction 2X(l)X(2) and show that they have all the properties mentioned above. (Think about the impracticality of carrying through the same procedure for a reaction with, say, five chemical components!)
Gas oil at 200 °C is to be cooled to 40 °C. The oil flow rate is 22,500 kg/h. Cooling water is available at 30 °C and the temperature rise is to be limited to 20 °C. The pressure drop allowance for each stream is 100 kN/m2 . Design a suitable exch..
Are the following processes exothermic or endothermic? after selecting the answer please explain why you selected it. a. When solid KBr is dissolved in water, the solution gets colder.
Product X takes 1 machine hour per unit and Product Y takes 5 machine hours per unit. Which of the following is one of the constraints for this linear program?
Design a vapor compression cycle using ammonia as the refrigerant that will be used to maintain the temperature of a stream at - 20 °C. The evaporator is air cooled and the ambient temperature may be assumed to be 25 °C. Assume a compressor effici..

The reflux is saturated liquid with L/D = 3. Feed is on the optimal stage. Vapor-liquid equilibrium data are given in Exercise 7.29.
You may assume the components and their mixtures to be in the ideal-gas state at the pressures and temperatures of this problem. Is this a reasonable assumption?
Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0C (called the molar heat capacity of silver). c. It takes 1.25 kJ of energy to heat a sample of pure silver from 12.0C to 15.2C. Calculate the mass of the sample of silv..
Neglecting stator resistance and rotational losses, and assuming constant rotor resistance, determine the slip at maximum torque and the slip at full load.
