An irreversible Isomerizationreaction AR is carried out in a liquid phase in MFR. Thereaction is first order and the rate constant at 165oC is 0.7 hr-1. The activation energy of thereaction is 120 kJ/mol and the heat of reaction is -350 kJ/kg. The heat capacity of thereactants and products are 1.95 kJ/kg-K, the volumetric flow rate is 0.33 m3/hr, and the feedtemperature is 20oC. If the conversion is 95%, calculate
(a) the reactor size and
(b) the temperature of the reaction mixture, if the reactor is operated adiabatically
Which alarms should activate a shutdown trip, and which valves should be closed?
Determine the current I through the 10-Ω resistor of the circuit of Figure P2.2.5 by employing the node-voltage method. Check by mesh analysis.
Principles associated with the theory of Creep and Viscoplasticity need to be identified and your understanding of these principles. Graphs, tables, calculation etc should be included for better illustration.
What temperature will be indicated by the thermocouple? Assume free convection from the thermocouple.
If the bore of the machine is 42 cm in diameter, its axial length is 28 cm, and each pole subtends an angle of 60°, determine the air-gap flux density. (Note that the number of parallel paths is equal to the number of poles for lap windings.)
If one of the machines has its field excitation adjusted such that it delivers 125 A lagging current, determine the armature current, power factor, excitation voltage, and power angle of each machine.
The complete combustion of acetylene, C2H2(g), produces 1300. kJ of energy per mole of acetylene consumed. How many grams of acetylene must be burned to produce enough heat to raise the temperature of 1.00 gal of water by 10.0C if the process is ..
A 50-kW, 230-V compound generator has the following data: armature-circuit resistance 0.05 Ω, series-field circuit resistance 0.05 Ω, and shunt- field circuit resistance 125Ω.
Determine the synchronous speed in revolutions per minute and the useful torque in new ton meters of a 200-hp, 60-Hz, six-pole synchronous motor operating at its rated full load (1 hp ≅ 746 W).
At a power angle of 30°, the power developed by the motor is 33 kW. Determine the reactive kVA of the motor, and the overall power factor of the motor and the load.
Calculate packing height required for the desired separation.
Take the saturation temperature of n-propanol at 2.1 bar as 118ŽC. The otherphysical properties required can be found in the literature, or estimated.
