Heat transfer is the movement of thermal energy from one object or system to another. This can occur in a variety of ways, including conduction, convection, and radiation. Each method of heat transfer plays a significant role in the everyday world, from cooking food on a stove to heating buildings …

A valve is a mechanical device that controls the flow of fluid and pressure within a system or pipe. A valve controls the system or processes fluid flow and pressure by stopping, starting, and Regulating it. Types of valves and their Classification Although all valves have the same basic components …

Some welding processes resemble both soldering and brazing and that molten metal is applied to produce a joint between the two pieces. However, in welding, the added metal is, more often than not, of similar composition to the metals being joined, and the joined pieces are melted locally so differences …

Today we will discuss about typical Mechanical Valve functions and basic parts of Valve. Valves are the most common single piece of equipment found in industrial facilities. Although there are many types, shapes, and sizes of valves, they all have the same basic parts. This chapter will review the common …
Read More »Positive Displacement Pumps types and operation
Positive displacement pumps operate on a different principle than centrifugal pumps. 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. A positive displacement pump is one in which a definite volume of liquid is …
