What is the difference between long radius 90 degree elbow and short radius 90 degree elbow?
The primary difference between a long radius (LR) and a short radius (SR) 90-degree elbow lies in the curvature and the radius of the bend. A long radius elbow has a center-to-end distance that is greater, typically 1.5 times the pipe diameter, allowing for a smoother flow of fluid and reduced turbulence. In contrast, a short radius elbow has a tighter bend, with a center-to-end distance that is equal to the pipe diameter, which can lead to increased pressure drop and turbulence in the flow. These characteristics make long radius elbows more suitable for applications where minimizing flow resistance is critical.
Is radius half radius?
No. Radius is half of the diameter.
How do you get from the radius to the circumference?
(radius+radius) times pi
What are three items that need to be calculated to determine the crane capacity at radius?
To determine the crane capacity at a specific radius, three key items must be calculated: the load weight, the crane's maximum rated capacity at that radius, and the moment arm distance. The load weight ensures that the crane can safely lift the intended load, while the maximum rated capacity indicates the crane's limits for that specific radius. The moment arm distance, which is the horizontal distance from the crane's pivot point to the load, is critical for calculating the leverage and stability of the lift.

What is the physical basis for existence of a critical insulation radius?
The general thinking is that with the increase in thickness of insulation around the system(say a pipe) the heat loss will always reduce.This is true only up to a certain radius of the insulation called the critical insulation radius.After this radius any increase in the thickness would in fact increase the heat loss.This happens because there are two phenomena taking place here viz. conduction and convection.Conductive resistance is dx/k i.e. thickness/conductivity with increase in thickness the conductive resistance increases hence heat loss decreases.Convective resistance is 1/hA,now beyond the critical radius the increase in conductive resistance is offset by the reduction in convective resistance.This is because with increasing radius one has also achieved a greater heat transfer area as A=2*pi*r*l.
What is the critical radius formula and how is it used in determining the stability of a system?
The critical radius formula is used to calculate the minimum size at which a system becomes stable. It is determined by the balance between internal and external forces. When the system's radius is smaller than the critical radius, it is unstable.
What is the definition of 'critical thickness'?
The thickness at which insulation begins to decrease heat loss is described as Critical Thickness
If radius of the earth is doubled then value of critical velocity becomes what?
The question cannot be answered because the question provides no information on the mass of the "new" earth. Also, if it is a more massive earth then it is more likely to have a denser atmosphere.
How degree of under cooling affect the critical size of nucleus in case of homogeneous nucleation?
In general, the greater the degree of undercooling of a liquid melt, the smaller the critical radius of the nuclei formed.
Does the insulation of wires affect its quality?
yes and no The problem is that the Word "Wire" refers to the both the metal core and the Wire as a conductor and insulation package. Another problem is what you mean by "quality". What definition are you using? The insulation is critical to determining the use and safety of a wire. The resistance of the metal wire is not affected by the insulation, but its ability to dissipate heat while carrying high current is.
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
What are five types of insulators?

What is floor insulation?

Why is server room critical?
A server room is an area set aside specifically to house the business' servers where all the information is accessed. It requires insulation and air conditioning so that the servers are not damaged by the environment.
