Question Number 1: Explain briefly the metering pumps?
Answer: Generally these types of reciprocating pumps are relatively small and light in weight. Small reciprocating pumps are fixed on a light structural frame and other pumps have metal base bolted with the floor. Tank mounted pumps need no foundation but the tank is to be fixed.
Question Number 2: What is the function of foot valve in a well?
· A foot valve, in relation to water well, is a check valve at his bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose its prime and will not pump water.
· It acts like a NRV. Prevents water flow back into the well and facilitates priming.
Question Number 3: what is BOOSTER pump which is used in power plant?
· Booster pump is used where high pressure is required. Normally onboard ships oil is feeded to IC engines via a feed pump and a booster pump in conjunction. Feed pump draws oil from the oil tank and its discharge is connected to the suction of booster pump to increase the pressure.
· This is used when oil is supposed to be injected at a high pressure into the engine. In general a screw pump is used as a booster pump.

Question Number 1: what is heat treatment and why is it done?
Answer: Heat treatment can be defined as a combination of processes or operations in which the heating and cooling of a metal or alloy is done in order to obtain desirable characteristics without changing the compositions. Some of the motives or purpose of heat treatment are as follows:
In order to improve the hardness of metals.
For the softening of the metal.
In order to improve the mach inability of the metal.
To change the grain size.
To provide better resistance to heat, corrosion, wear etc.
Question Number 2: Why do heavy vehicles use diesel engine?
Answer: The compression ratio of diesel engine is higher than the petrol engine, the reason for producing higher torque. The efficiency of diesel engine increases with load. Diesel produces slow energy on burning of fuel and the efficiency of the engine increases with load which is why diesel engine is suitable and largely used for heavy vehicles
Question Number 3: what are types of heat treatment?
Answer: Heat treatment is generally performed in the following ways:
