Caraga Regional Hospital Interview Questions and Answers

Questions related to pumps, flow meters, distillation column, and heat transfer modes.

• Pumps are devices used to move fluids by mechanical action.

• Flow meters are instruments used to measure the flow rate of fluids.

• The working of flow meters varies depending on the type of flow meter used.

• Increasing the reflux ratio in a distillation column increases the purity of the distillate.

• The modes of heat transfer are conduction, convection, and radiation.

Broaching is a machining process used for shaping a surface by removing material with a toothed tool.

• Broaching is a metal cutting process that uses a toothed tool called a broach to remove material from a workpiece.

• It is used for shaping internal or external surfaces, such as keyways, splines, and gears.

• Broaching can be used as a finishing process to achieve tight tolerances and smooth surface finishes.

• It can also be used as a roughing process to remove large amounts of mater...read more

There are two main types of IC engines: spark ignition (SI) engines and compression ignition (CI) engines.

• Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly used in gasoline engines.

• Compression ignition (CI) engines rely on the heat generated by compressing the air-fuel mixture to ignite it, commonly used in diesel engines.

• Other types include rotary engines, two-stroke engines, and four-stroke engines.

• Rotary engines, also known as Wankel eng...read more

A heat exchanger is a device used to transfer heat between two or more fluids.

• Heat exchangers are used in various industries such as chemical, power, and HVAC.

• They work by allowing two fluids to flow through separate channels, with heat transferring from one fluid to the other.

• Common types of heat exchangers include shell and tube, plate and frame, and finned tube.

• Heat exchangers can be used for heating, cooling, or both.

• Efficiency of a heat exchanger is determined by factors...read more

Flow meters are devices used to measure the flow rate or quantity of a gas or liquid moving through a pipe.

• Differential pressure flow meters

• Positive displacement flow meters

• Velocity flow meters

• Mass flow meters

• Open channel flow meters

Distillation is a process of separating components of a mixture based on their boiling points.

• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.

• Examples include the distillation of crude oil to produce gasoline and the distillation of alcoholic beverag...read more
