Which of the following boiler arrangements will ensure that there is NO contamination of the primary feed system?
Show Hint
- Steam-to-steam generator
- Double evaporation boiler
- Water tube boiler
- Fire tube boiler
The Correct Option is A, B
Solution and Explanation
Steam-to-steam generators and double evaporation boilers separate the primary and secondary circuits, preventing contamination of feedwater. Step 2: Others allow direct contact.
Water tube and fire tube boilers may allow feedwater contamination due to single circuit exposure.

A ship of 3300 tonne displacement is undergoing an inclining experiment in seawater of density 1025 kg/m\(^3\). A mass of 6 tonne is displaced transversely by 12 m as shown in the figure. This results in a 0.12 m deflection of a 11 m long pendulum suspended from the centerline. The transverse metacenter of the ship is located at 7.25 m above the keel.
The distance of the center of gravity from the keel is ________ m (rounded off to two decimal places).
