Design a shell and tube exchanger for the following duty.
20,000 kg/h of kerosene (42° API) leaves the base of a kerosene side-stripping column at 200 °C and is to be cooled to 90 °C by exchange with 70,000 kg/h light crude oil (34° API) coming from storage at 40 °C. The kerosene enters the exchanger at a pressure of 5 bar and the crude oil at 6.5 bar. A pressure drop of 0.8 bar is permissible on both streams. Allowance should be made for fouling by including a fouling factor of 0.0003 (W/m2 °C)-1 on the crude stream and 0.0002 (W/m2 °C)-1 on the kerosene stream.
Determine the Probability that an Ahmed energy state is occupied by an election it the slide is above the Fermi level by KT.
Derive an expression for the optimum economic thickness
Now suppose a 10-mm air gap is cut across the toroid. Determine the current that must be supplied to the coil to produce the same value of magnetic flux density as in part (a). You may neglect leakage and fringing.
Fresh rainwater or surface water contains enough tritium ( ) to show 5.5 decay events per minute per 100. g of water. Tritium has a half-life of 12.3 years. You are asked to check a vintage wine that is claimed to have been produced in 1946.
In a process for the production of acrylic fibers by the emulsion polymerization of acrylonitrile, the unreacted monomer is recovered from water by distillation. Acrylonitrile forms an zoetrope with water and the overhead product from the column c..
Mass of Air Required for Combustion of Fuel. A coal fired boiler uses fuel having the following analysis by mass:
A 50-kW, 250-V, short-shunt compound generator has the following data: Ra = 0.06 Ω, RS = 0.04 Ω, and Rf = 125 Ω. Calculate the induced armature voltage at rated load and terminal voltage. Take 2 V as the total brush-contact drop.
High-density polyethylene may be chlorinated by inducing the random substitution of chlorine atoms for hydrogen.
Hydrogen gas at a pressure of 1.25 bar is contained in a thick-walled neoprene rubber sphere which has inner and outer radii of 70 mm and 80 mm, respectively.
A four-pole, dc series motor has a lap-connected, two-layer armature winding with a total of 400 conductors. Calculate the gross torque developed for a flux per pole of 0.02 Wb and an armature current of 50 A. (Note: The number of parallel paths i..
How have the technological advances in personal computing made this conversion faster and the speech output more lifelike?
One mol of methanol vapor is cooled under constant pressure in a closed system by removing 25000 J of heat. Initially, the system is at 2 bar, 200 °C.
