Inside a tube with streamline fluid flow temperatures are relatively constant.

Plate and frame heat exchangers are easy to clean and have high heat transfer coefficients.

A shell and tube heat exchanger can be used to heat and cool a substance.

List the parts of a floating head heat exchanger.

A layer of fluid that tends to adhere to the walls of a heat exchanger is referred to as:

Draw a plate and frame heat exchanger. Identify each component! Show all flows!

On a simple shell and tube heat exchanger a process technician would turn the device into a bomb if he closed which of the following valves first.

Plate and frame heat exchangers tend to foul easily because they have close clearances and low pressure drops across the plates.

Heat exchanger effectiveness is linked to all of the following except:

Internal buildup on the surface area of a heat exchanger that results in a restriction is referred to as:

Turbulent flow allows molecules of fluid to mix and absorb heat energy better than laminar but it enhances the stationary film along the shell and tube walls.

A baffle that is designed to deflect high velocity fluids inside a heat exchanger.

A term used to describe flow in a heat exchanger where tube-side flow and shell-side flow go in the same directions.

A term used to describe flow in a heat exchanger where shell-side flow vertically crosses the horizontal tube flow.

Draw a U-tube heat exchanger. Do not list parts. Show flows

A type of heat exchanger that uses a tubular bundle to heat and flash a liquid in an over-sized shell with a vapor disengaging cavity.

The tub head on a floating head heat exchanger is firmly attached to the tube sheet.
