Question - 22 25 tons of caustic solution having 10 % concentration was fed to an evaporator . the concentrated liquor leaving the evaporator contains 50% NaOH , 2 % Nacl and 48 % H2O .
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, ift..
An electric motor under steady load draws 9.7 amperes at 110 volts; it delivers 0.93 Kw of mechanical energy. The temperature of the surroundings is 300 K. What is the total rate of entropy generation in W K-1?
Important information about Vapor pressure, At the top of Long's Peak in the Rocky Mountains (a) what is the vapor pressure if boiling a container of eggs (without a lid) occurs
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.
Estimate the annual operating cost of providing refrigeration to a condenser with duty 1.2 MW operating at -5 ºC. The refrigeration cycle rejects heat to cooling water that is available at 40 ºC, and has an efficiency of 80% of the Carnot cycle ef..
Explain in detail why this is the case, what the challenges are in terms of developing a successful small diameter vascular prosthesis and why you think this goal has yet to be achieved
What is the optimum practical shape for an above-ground dwelling to minimize the heat losses through the building fabric? When is (or was) this optimum shape used? Why is this optimum shape seldom used in richer societies?
A drug (D) is produced in a three-stage extraction from the leaves of a tropical plant. About 1000 kg of leaf is required to produce 1 kg of the drug. The extraction solvent (S) is a mixture containing 16.5 wt% ethanol (E) and the balance water (W..
If the gases leave the tower at 6 atm, 25 °C, and are expanded to, say, 1.5 atm, calculate the turbine exit gas temperatures without preheat, and if the gases are preheated to 400 °C with the reactor off-gas. Also, estimate the power recovered fro..
Compute the efficiency at one-half load, assuming that the stray-loss and rotational losses do not change with load.
