3. Derive Bernoullis Equation and explain the following terms: 20
(a) Gravity head
(b) Pressure head
(c) Kinetic Energy Correction factor
4. Explain the following: 20
(a) Thermal boundary layer
(t>) Working of counter current and co-current heat exchangers
(c) AMTD and LMTD
5.. Discuss the steps involved in the transfer of oxygen from gas bubble to
f
the individual cells, also explain the significance of KLa and how it is determined. 20
6. Anaerobic digestion of volatile acids by methane bacteria is represented by the following equation : 20
CH3 COOH + NH3 - biomass + C02 + H20 + CH4
(Methane)
The composition of Methane bacteria is approximated by the empirical formula CH14 O0.4 N0.22- For each kilogram acetic acid consumed
0.67Kg Carbon dioxide is evolved. How does the yield of methane compare with the maximum possible yield?
