Vapor Absorption Vs Vapor Compression Refrigeration
There are some aspects in which vapor absorption refrigeration system is different from that of vapor compression. The main principle is the same for the two systems. But there are differences between power consumption COP, mechanical parts etc. Have a look Mechanical Engineering Interview Questions part – 1 Mechanical Engineering [...]
Ten Tools Every Welder Wants
This article is all about the tools that welders want to have in their shop. They make welding easier, and in many cases, they make the welding process — from start to cleanup — more enjoyable. If you’re new to welding and you have a birthday coming up, you’re going to want to start dropping hints about these tools to your family. As [...]
Limiting Friction Explained – Laws of Limiting Friction
a force acting on the opposite direction to the motion of the body is known as friction or force of friction. Friction can be of the following two types. Static Friction 2. Dynamic Friction The friction experienced by a body when at rest is known as static friction. The friction experienced by a body when at is known as dynamic friction. [...]
How does Plate and Frame Heat Exchanger Work
Different innovative heat exchangers are designed according to application. Various types of hardware arrangements and configurations are needed for the heat transfer equipment. Equipment are needed to be designed to match the hardware with the requirements. The double heat exchanger is the one which uses two concentric pipes of [...]

A Complete Guide to Fluid Mechanics Fundamentals and Applications
In this section, we introduced the physical properties of fluids, the distinction between laminar and turbulent flows, and the forces that are known as buoyancy, drag, and lift. Mechanical engineers categorize substances as being either solids or fluids, and the distinction between the two centers around how they respond to a shear [...]
Aerodynamics in Sports
When a ball is hit, thrown, or kicked in sports, the ball’s trajectory can rapidly change direction.In baseball, this phenomenon is the strategy behind curve ball pitches; in golf, it is responsible for slicing or hooking a ball driven off a tee; and in soccer, the ball can be “bent” during a free kick to outmaneuver the goalie. Cricket [...]
Lift Force – Aerodynamics Fundamentals
LIFT FORCE Similar to drag, the lift force is also produced by the relative motion between a solid object and a fluid. While the drag force acts in parallel to the direction of the fluid’s flow, the lift force acts in perpendicular to it. For instance, in the context of the airplane shown in Figure 6.26, the high-speed flow of air around [...]
