In ships, a flash evaporator is used to obtain ________.
Show Hint
- distilled water
- low viscosity lubricating oil
- high-temperature heavy oil
- air for space heating
The Correct Option is A
Solution and Explanation
A flash evaporator operates on the principle of sudden pressure drop, which causes water to flash into steam and then condense into pure distilled water.
Step 2: Application in marine systems.
On ships, flash evaporators are widely used to produce fresh (distilled) water from seawater, especially for drinking and boiler feed.
Correct Answer: (A) distilled water.

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).

Consider a weightless, frictionless piston with a 2 kg mass placed on it as shown in the figure. At equilibrium in position 1, the cylinder contains 0.1 kg of air. The piston cross-sectional area is 0.01 m2. The ambient pressure in the surroundings outside the piston-cylinder arrangement is 0 bar (absolute). When the mass above the piston is removed instantaneously, it moves up and hits the stop at position 2, which is 0.1 m above the initial position.
