If the diameter of a pipe in a fluid system decreases, the pressure of the fluid will do this.

What is decrease?

100

Valve used to make relatively fine adjustments in the rate of fluid flow

What is a needle valve?

100

Designed to cool a process stream on the tube side and use the heat removed from the process to boil water on the shell side

What is a waste heat boiler?

100

Proportional to speed or impeller diameter

What is pump capacity?

100

Three things that have the greatest effect on heat transfer  

What are temperature difference, surface area, and flow rate?

200

Moving a control valve from 70% to 50% open will have this effect on pressure across a control valve

What is increased pressure drop?

200

Retains steam in the tracing for heating the process and releases steam condensate, air and non-condensable gases

What is a steam trap?

200

Blocked tubes, deposits and corrosion    

What are results of fouling?

200

Centrifugal pump head decreases as pump capacity (or flow rate)

What is increases?

200

Fluctuation in flow; erratic discharge pressure; higher than normal vibration levels; noise similar to pumping stones

What are indicators of cavitation?

300

If the diameter of a pipe in a fluid system decreases, the velocity of the fluid will do this.

What is increase?

300

Valve that automatically prevents any significant flow reversal

What is a check valve?

300

Type of exchanger that has a stationary tube sheet at the channel end and a floating tube sheet at the rear end

What is a floating head exchanger?

300

This type of pump cannot be operated with the discharge valve shut

What is a positive displacement pump?

300

Pressure spike that travels at the speed of sound along the length of the piping; liquid flowing through a line stops suddenly; sudden spike in pressure that can be of high magnitude and short duration

What is piping surge?

400

Moving a control valve from 70% to 50% open will have this effect on flow across a control valve

What is less flow?

400

Ball float rises and lowers with condensate level opening and closing the valve

What is a mechanical steam trap?

400

Designed to convert a vapor stream into a liquid  

What is a condenser?

400

In a centrifugal pump, this whirls the liquid in a circular motion to add energy to the fluid  

What is an impeller?

400

What piece of equipment is designed to withstand operating conditions, type of process, and regeneration conditions?

What are reactors?

500

Done to ensure open flow path for proper function of pressure relief valve

What is car seal PRV inlet and outlet valves open?

500

Must be removed from piping system during flushing and hydrotesting; installed so indicators are readable from normal personnel access paths; not located neat hot surfaces unless thermal shielding is used; may be mounted above grade if a platform for access is provided

What is a control valve?

500

The transfer of heat from the surface of a heat exchanger tube to the fluid flowing around the tube

What is convection?

500

This is where the liquid enters the impeller of a centrifugal pump

What is the eye?

500

Close low point drains after system is at normal temperature and pressure; drain condensate from piping or systems to be commissioned; allow system to slowly warm up; ensure all steam traps on system are commissioned and operating

What are steps used to prevent liquid/water hammer?
