District of Columbia Mechanical and Ethics 20 PDH Discount Package 2

This online engineering course provides necessary information to understand the principles and theory of refrigeration, the components of mechanical refrigeration systems, and the types of refrigerants and associated equipment. This course also discusses the methods used for installing, maintaining, and repairing refrigeration equipment, including domestic refrigerators and freezers.

Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.

This online engineering course presents the basic principles of hydraulics and pneumatics along with their various components followed by discussing the maintenance procedures associated with these systems.

In automotive and construction equipment, the terms “hydraulic” and “pneumatic” describe a method of transmitting power from one place to another through the use of a liquid or a gas which obey certain physical laws and principles discussed in this course.

This online engineering course presents the operational principles and basic mechanisms of the internal combustion engine.

The power of an internal combustion engine comes from burning a mixture of fuel and air in a small, enclosed space. When this mixture burns, it expands significantly; building pressure that pushes the piston down, in turn rotating the crankshaft. Eventually, this motion is transferred through the transmission and out to the drive wheels to move the vehicle.

The automobile is a familiar object to all of us. The engine that moves it is one of the most fascinating and talked about of all the complex machines we use today. This machine is what we call the internal combustion engine.

This online engineering PDH course explains the operation of centrifugal and positive displacement pumps. In general a pump is a mechanical device that is used to raise the flow of a fluid from one elevation to the other by increasing the pressure of the fluid.

Centrifugal pumps use a centripetal force, which is defined as the action that causes the fluid to move away from its center of rotation. Where as positive displacement pumps physically entrap a quantity of liquid at the suction of the pump and push that quantity out the discharge of the pump.

This 3 PDH online course is applicable to mechanical engineers, plant operators, maintenance personnel, and technical staff who are interested in gaining a better understanding centrifugal and displacement pump design and operation.

This online engineering PDH course provides a comprehensive overview of methods to find the true cost of steam. 

In industrial manufacturing facilities, process heating accounts for an average of more than 60% of thermal energy use, predominantly in the form of steam. Process heating also accounts for a significant portion of controllable operating costs. It is one of the few areas of opportunity where management can reduce operating costs and improve profits. This course examines different methods to calculate the cost of steam and compares the results showing how the model method is a recommended approach.

In this online engineering PDH course, ten case studies of actual enforcement actions taken by a state licensing board are presented. The cases have been selected to be representative of situations likely to exist in many states.  Board procedures and the types of enforcement actions available are shown by a variety of cases ranging from a geotechnical engineer who produced (within one hour and without visiting the site) a soils report, to an engineer who was unable to document his PDH's during a board audit.  The importance of being very careful about when to put "P.E." after one's name on a document also will become apparent.

Codes of ethics for engineers typically describe standards for professional behavior. The enforcement of those ethical standards that are inscribed into law lies with the licensing boards of state governments.

This 1 PDH online course is intended primarily for all engineers seeking to deepen their understanding of what constitutes ethical and professional engineering behavior and how such behavior is enforced by the licensing board.
