Task 2: File Deletion and Recovery
Create a sparse FAT filesystem image named recovery. img using mkfs. fat. You can choose the size of the
filesystem as long as it is less than 2GB.
Copy 3 files of your choice into the filesystem, e.g., by using mcopy or by mounting the filesystem and
using cp. Note that the size of each file must be between 4KB and 6KB.
Pick one of the files (say foo.jpg) and identify which byte offsets and which clusters are used to store it
using mshowfat. The ranges that you give should be inclusive of the last byte/cluster. Record your answers in a
file named recovery.txt with a table of this form:
FILENAME: foo.jpg
byte offset range | cluster range
0x04200-0x047ff
0x06400-0x0651c
2-4 |
19-19 |
Now find the part of the File Allocation Table that corresponds to your choice of file. Add a hexdump of the
part of File Allocation Table you find to your file recovery.txt and annotate it to show the clusters. If you
have a FAT12 filesystem, then it can look like the…

A CO₂-saturated brine (ionic strength = 2.5 mol/kg, pH = 3, a_H⁺ = 0.01) flows at 2 cm/s through a horizontal tubular reactor (L = 1 m, D = 0.05 m) packed with 5 kg of olivine (Zhuravlev-BET surface area = 30 m²/g). The system operates at 90 °C and 40 bar, and external mass transfer resistance is negligible. The rate-limiting step is electron transfer at the mineral surface, governed by Marcus theory, with λ = 0.75 eV, ΔG° = –0.30 eV, and k₀ = 10⁶ s⁻¹. The Mg²⁺ activity coefficient is γ = 0.76 (from PHREEQC with Pitzer model). For Mg₂SiO₄ + 4 H⁺ → 2 Mg²⁺ + SiO₂(aq) + 2 H₂O, determine the total moles of Mg²⁺ released after 10 minutes at steady state.

- A 0.45 mol/kg aqueous solution of 3-(methylamino)propylamine and 1-methylpiperazine (1:1 molar) flows at 0.5 g/s through a 2.5 m horizontal stainless steel coil (inner diameter 1.2 mm), entering at 358.15 K and 22 MPa and exiting at 20 MPa. A constant wall heat flux of 28 W is applied. Local density and isobaric heat capacity are obtained through from the Benedict–Webb–Rubin equation of state, with a 3% increase in heat capacity to account for wall sorption. Dynamic viscosity is obtained using the Green-Kubo relation with a given integral value of 2.1 × 10⁻¹⁰ Pa².s, and thermal conductivity is assumed constant. The local Nusselt number is corrected for thermal development using Nu(x) = 3.66 + (0.065 · Gz(x)^0.7) / (1 + 0.04 · Gz(x)^0.7), where Gz(x) = D · Re(x) · Pr(x) / x.
