(a) Determine the molar ratio of hydrogen to carbon in the fuel (r), where
(b) What is the air-to-fuel ratio (m3air/kg of fuel) if the air is fed to the power plant at 30°C and 98 kPa?
(c) The speci?c gravity of the fuel (a petroleum product) is 0.85. Estimate the ratio standard cubic feet of gas fed to the turbine per barrel of fuel.
Exploratory Exercise—Research and Discover (d) What are the issues associated with using oil as a fuel as opposed to natural gas‘? Consider two factors: (i) the complete composition of typical fuel oils and their resulting emissions, and (ii) the availability and global distribution of the two fuel sources.

A forward feed double-effect vertical evaporator, with equal heating areas in each effect, is fed with 5 kg/s of a liquor of specific heat capacity of 4.18 kJ/kg K. and with no boiling point rise, so that 50 per cent of the feed liquor is evaporated. The overall heat transfer coefficient in the second effect is 75 per cent of that in the first effect. Steam is fed at 395 K and the boiling point in the second effect is 373 K. The feed is heated by an external heater to the boiling point in the first effect. It is decided to bleed off 0.25 kg/s of vapour from the vapour line to the second effect for use in another process. If the feed is still heated to the boiling point of the first effect by external means, what will be the change in steam consumption of the evaporator unit?
