In this episode, we discuss forced convection under laminar flow conditions. Since there are no eddies in laminar flow, heat transfer occurs primarily through conduction. Based on this, we examine how heat transfer behaves in a circular pipe for both plug flow and thermally fully developed flow.
The temperature of an object does not necessarily remain constant during heat conduction. In this episode, we focus on the mathmatical modeling of conduction under unsteady state. Using partial differential equations (PDEs) in various coordinate systems- Cartesian, cylindrical, and spherical-we discuss how the temperature of an object changes over time.
This episode covers conduction-one of the three modes of heat transfer. We start by examining thermal conductivity and derive the general conduction equation. Finally, we discuss how to calculate conduction under steady-state conditions for specific scenarios.
In industrial systems, temperature is a critical process variable, affecting equipment performance and process efficiency. Achieving the desired temperature requires an understanding of heat transfer principles. In this episode, we provide an overview of the three modes of heat transfer and their fundamental characteristics.
Liquid mixtures can exist in a single phase. However, they may also separate into multiple liquid phases. This episode covers liquid-liquid phase equilibrium under constant temperature and pressure. First, we determine the conditions for liquid-liquid phase equilibrium using fugacity. We then examine the Gibbs free energy behavior in phase equilibrium,.
The bimatallic thermometer is a widely used type of thermometer that operates based on the difference in thermal expansion between two metals. In this episode we describe how bimetal strips respond to temperature changes depending on their configuration and introduce the features of bimetallic thermometers.
A pressure relief valve is a device designed to protect a system from overpressure, commonly used in high-pressure systems. Selecting the appropriate valve size is crucial for effective pressure release. This episode covers how to size a pressure relief valve based on fluid type.
Selecting an appropriate-sized valve is essential to achieve the desired flow rate. In this episode, we discuss how to size control valves based on the phase of the fluid.
There are many types of valves, but the common factor we need to check is whether the valve can pass the desired amount of fluid. This episode introduces flow and resistance coefficients, which help determine how much flow a valve can handle. Finally, we discuss valve flow characteristics and their different types.
The reciprocating pump is a well-known type of positive displacement pump, often considered when pumping high-viscosity fluids or when high pressure is needed. In this episode, we look at the basic principles and key features of reciprocating pumps and discuss the additional factors for calculating NPSH in these pumps.
