Residual Pressure
Residual pressure is a concept common with water supply systems. It refers to the pressure remaining in a pipe during flow conditions. This contrasts with static pressure, which is the…

David Etukudo Engine Load – Definition, Calculation, vs. RPM, at Idle
An engine load determines the demand put on an engine’s capacity to produce power. Moreover, the load provides specification guidance to manufacturers as they design engines to ensure that they…
Pipe Invert Elevation
Pipe invert elevation is the vertical distance between the inside-bottom of a pipe and a given benchmark. Moreover, the term ‘invert’ stems from the resemblance of the pipe bottom to…
Gasoline Boiling Point – Blends, Pressure, and Weather Considerations
At atmospheric pressure, gasoline has an initial boiling point of 95 °F (35 °C) and a final boiling point of 395 °F (200 °C). This wide range is due to…
Is Statics a Hard Class?
Statics is a class that deals with the application of Newtonian physics and serves as an entry point into engineering mechanics. Typically, mechanical and civil engineers take the class as…
Stebin Samuel Isentropic
Isentropic is a term that describes a process during which the entropy of the system remains constant. In thermodynamics, isentropic refers to an idealized process, where work transfers of a…
What is the Clausius Inequality?
To understand what the Clausius Inequality is, one must first look at a thermodynamic system, which exchanges heat with its environment. The Clausius Inequality relates the change in entropy of…
Helical Spring Constant – Formula, K Factor, Parameters, and Applications
The helical spring constant, more commonly referred to as the k value, provides key information about a spring’s stiffness capacity. A greater k value is indicative of a greater restoration…
Is Heat a State Function?
Is heat a state function? The answer is no. Heat is the energy transferred between the system and the surroundings during a process. The amount that transfers does depend on how the…
Graham Garcia Is Thermal Energy Potential or Kinetic?
Thermal energy refers to the energy that a body or system has due to the movement of its particles. So, is thermal energy potential or kinetic? The answer lies in…
