How Pressure Cooker Works?
If the pressure of a substance is increased during a boiling process, will the temperature also increase or will it remain constant? Why? Ans: If the pressure of a substance increases during a boiling process,…

Basic Terms to Know Before Starting Thermodynamics
Classical and the statistical approaches to thermodynamics: Classical thermodynamics is based on experimental observations whereas statistical thermodynamics is based on the average behaviour of large groups of particles. The light-year: In this unit, the word…
Basic Terms to Know Before Starting Fluid Mechanics
Fluid: A fluid deforms continuously under the influence of shear stress, no matter how small . Internal flow: The flow in a pipe or duct is internal flow if the fluid is completely bounded by…
Why Must We Reject Heat Qout in a Heat Engine?
After the working fluid expands and produces work. Therefore, the working fluid is still hot. To reuse it again, the fluid must be cooled back through leaving the heat to a heat Sink or in…
Acceleration Field
The fundamental conservation laws—such as the conservation of mass and the first law of thermodynamics—are formulated for a fixed-identity collection of matter, known as a closed system in thermodynamics. However, analyzing a control volume (or open system) is often…
DENSITY AND SPECIFIC GRAVITY
Density is defined as mass per unit volume (Fig. 2–3). That is,Density: (2–1) The reciprocal of density is the specific volume v, which is defined as volumeper unit mass. That is, v ! V/m !…
What Is a Fluid?
What Is a Fluid? You will recall from physics that a substance exists in three primary phases: solid, liquid, and gas. (At very high temperatures, it also exists as plasma.) A substance in the liquid…
Verification of Bernoulli’s Equation.
Experiment Name: Verification of Bernoulli’s Equation. Abstract: This experiment was conducted to verify Bernoulli’s equation using a Venturi meter. Water flow through the test section was measured at different points using manometer tubes and a…
