A shell-and-tube heat exchanger with one shell pass and two tube passes employs condensing steam at 1 atm on the shell side to heat 10 kg/s of engine oil from 50 to 60°C in the tubes. The steam enters as saturated vapor and leaves as saturated liquid with hfg=2.26 MJ/kg. The hot condensate leaving the exchanger is subsequently used to heat water to 60°C in another shelland-tube exchanger, with the condensate occupying the shell side and the cooler water flowing in the tubes. The cool water enters at 20oC.
1. Make your suitable selection for the tube materials and sizes (diameter, thickness) of both exchangers.
2. Determine values of U for both heat exchangers. Do not neglect wall resistances and take into account the fouling inside of tubes.
3. Determine the size of the steam condenser and suggest sizes for the exchanger which serves as the water heater. Please consider the space limitations and cost of manufacture (in practice, the desirable tube length must be less than 2 m).
4. For each exchanger suggested, indicate the amount of water which may be heated.
5. Comments on the suggested tube arrangements
Design the width of the fusing section so that it will break at currents above I = 20 A This design is typical of automotive fuses (although pure copper is almost never used because of oxidation problems).
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..
Determine whether the claimed performance of the process is consistent with the second law. Assume that air is an ideal gas for which Cp = (7/2)R.
Which subfields are contained in GF(625)? Let a be a primitive element in GF(625). Which powers of α constitute the various subfields of GF(625)?
question 1suppose the system shown below. initially the gas is at 200 kpa and occupies a volume of 0.1 m3. the spring
The enthalpy change of reaction for the balanced equation (with lowest whole-number coefficients) is H 67.7 kJ. If 2.50 102 mL of N2(g) at 100.C and 3.50 atm and 4.50 102 mL of O2(g) at 100.C and 3.50 atm are mixed, what amount of heat is..
Finding the Heat of Reaction (Enthalpy) from Heats of Formation, Calculate the heat of reaction at the standard reference state for the following reactions
Commercial cold packs and hot packs are available for treating athletic injuries. Both types contain a pouch of water and a dry chemical. When the pack is struck, the pouch of water breaks, dissolving the chemical, and the solution becomes either ..
The steady - state passive current density for iron in 1 N H 2 SO 4 is 7 µ A/cm 2 . How many atom layers of iron are removed from a smooth electrode surface every minute?
Design a Linde process to liquefy oxygen. Pure oxygen is supplied at 1 bar, 25 °C and liquid oxygen is received at 1 bar. The fluid is compressed to 150 bar in a series of compressors whose efficiency is 80%. Precooling is done by water at 20 °C. ..
Steam enters a cooling tower at 200 °C and exits at 60 °C. Cooling is supplied by the surroundings which are assumed to be at 30 °C. The process takes place under atmospheric pressure (1 bar).
The concentration of this sample is changed such that its transmittance has increased to 57%. Calculate the new concentration of the sample.
