(1) Deduce the expressions relating pE to pH, the concentration of sulfate ion, and the partial pressure of hydrogen sulfide gas, given that for the half-reaction, pE° = —3.50 V when the pH is 7.0.
(2) Deduce the partial pressure of hydrogen sulfide when the sulfate ion concentration is 1Q^5 M and the pH is 6.0 for water that is in equilibrium with atmospheric oxygen.

A syngas fuel consists of these following volumetric
composition: 75% methane and 25% butane. The syngas at 100 kg/hour
and 25oC is mixed with 20% excess air at 30oC. Due to incomplete
combustion mechanics, 10%v of the syngas carbon is partially
oxidized and forms carbon monoxide.
If the products of combustion are at 600K, obtain the combustion
heat transfer rate from the system.

It is recommended that drinking water contain 1.6 ppm of fluoride. If the local reservoir has a diameter of 450.0 m and a depth of 10.0 m (V= Pi*r2 *h), how many grams of F should be added to the water in the reservoir to give the recommended concentration? If fluoride is provided by hydrogen hexafluorosilicate (H2SiF6), how many grams of H2SiF6 contain Fluoride?

Q. No 3. The pressure drop Dp over a length L of pipe is assumed to depend on the average velocity V, the pipe’s diameter D ,the average height h of the roughness elements of the pipe wall, the fluid density ρ ,and the fluid viscosity µ .Write a relationship between the pressure drop and the other variables. Use Indicial Method (Rayleigh’s Method) only.

Three equal impedances, (8+j6) ohms are connected in wye across a three-phase, three-wire supply. The symmetrical components of the phase A line voltages are:
Va0 = 0
Va1 = 220 + j 28.9 V
Va2 = -40 - j 28.9
If there is no connection between the load neutral and the supply neutral, Calculate the symmetrical currents of line a,b, and c.
