In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. The unreacted ethylene is not recovered.
You have a heat pump that takes in 256 kW of heat and puts out 604 kW of heat. What is the coefficient of performance (C.O.P.) of the system ( express this value as a fraction)?
The equilibrium constant should vary with temperature according to the relation Kp = ae-b/T use the results of part (b) to determine the values of a and b by a graphical curve-fitting procedure. [Suggestion: Use the spreadsheet program from part (..
Equal rates of mass transfer for the production of the fine chemical are required. This is often required for certain types of organic synthesis.
show that the rotor current, torque, and electromagnetic power of a poly phase induction motor vary almost directly as the slip, for small values of slip.
Calculate the required value of Ta1 if the film temperature falls to 34°C, and the value if it rises to 36°C.
Water is pumped at a flow rate of 2.25 kg/min from 1 bar 20 °C to 15 bar. Determine the amount of work and the temperature of water at the exit if the efficiency of the pump is 78%.
Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
Because of failure in the insulation there is a loss of 60 kJ per kg of steam. What is the power produced by the turbine if all inlet and outlet conditions remain the same?
Calculate the size of the current pulse applied at 6 ms for 1 ms, necessary to raise Vm to 40 mV.
Design a condenser for the following duty: 45,000 kg/h of mixed light hydrocarbon vapors to be condensed. The condenser is to operate at 10 bar. The vapor will enter the condenser saturated at 60 °C and the condensation will be complete at 45 °C.
