A brine is used to measure the absolute permeability of a core plug. The rock sample is 4 cm long and 3 cm 2 in cross section. T
nydimaria [60]

Answer : The absolute permeability is, 0.111 darcys.

Explanation : Given,

Volumetric constant rate = 0.5cm^3/s

Cross section area = 3cm^2

Pressure = 2 atm

Viscosity = 1.0 cp

Length of rock = 4 cm

From the Darcy equation  we conclude that,

\text{Volumetric constant rate}=\frac{(\text{Absolute permeability}\times A\times P)}{\eta \times l}

where,

A = cross section area

P = pressure

\eta = viscosity

l = length of rock

Now put all the given values in the above formula, we get:

0.5cm^3/s=\frac{(\text{Absolute permeability}\times 3cm^2\times 2\text{ atm})}{1.0cp \times 4cm}

\text{Absolute permeability}=0.111\text{ darcys}

Therefore, the absolute permeability is, 0.111 darcys.

A chemist is given a sample of the CuSO4 hydrate and asked to determine its the empirical formula. The original sample weighed 4
Firlakuza [10]

Answer: The formula for this hydrate is CuSO_4.5H_2O

Explanation:

Decomposition of hydrated copper sulphate is given by:

CuSO_4.xH_2O\rightarrow CuSO_4+xH_2O

Molar mass of CuSO_4 = 160 g/mol

According to stoichiometry:

(160+18x) g of CuSO_4.xH_2O decomposes to give 160 g of anhydrous CuSO_4

Thus 42.75  g of CuSO_4.xH_2O decomposes to give=\frac{160}{160+18x}\times 42.75g of anhydrous CuSO_4

\frac{160}{160+18x}\times 42.75=27.38

x=5

Thus the formula for this hydrate is CuSO_4.5H_2O
