How do you calculate density for LTL freight?
How do you calculate density for LTL freight?
Divide the weight (in pounds) of the shipment by the total cubic feet. The result is the pounds per cubic foot, i.e., density.
How is NMFC code calculated?
To find the NMFC number that applies to your specific shipment, consult with the freight company you are using to ship your package. It will be able to help you classify your shipment and determine shipping costs.
What is a freight class code?
What is a freight class/NMFC code? Your less-than-truckload (LTL) freight shipping class is a number established by the National Motor Freight Classification (NMFC). * It’s calculated based on how difficult your commodity is to ship and how much liability is involved. Classes are a freight shipping industry standard.
What is freight class 85 description?
Class 85 (12-13.5 pounds per cubic foot) – Automobiles engines, cast iron stoves, crated machinery. Class 92.5 (10.5-12 pounds per cubic foot) – Computers, monitors, refrigerators, ice machines. Class 100 (9-10.5 pounds per cubic foot) – Calculators, wine cases, canvas, furniture.
What is freight Class 75?
The simplest way to think of it is, the lower the freight class, the lower the shipping price. A class 75 item will be cheaper than a class 400 item. There are two ways classification is made. Items that are classified by density and items that have a permanent class not based on weight or size, such as a transmission.
How to calculate freight density?
How to calculate Freight Density? Weigh the whole package in pounds (lbs). Measure the length, width, and height of the box in inches. Multiply these three dimensions to get the volume in cubic inches and divide by 1728 to determine the volume in cubic feet (1728 in3 = 1 ft3). Divide the weight by the volume to get the density in lb/ft3.
Where can I find the density of a refrigerant?
You can also use REFPROP software from NIST. It will not cost more. You will find the liquid density or two phase mixture density for any combination of refrigerants and gases too.
What is freight class and how is it calculated?
Freight class is based on four factors. 1. Density: The space the items take up in the trailer and their weight factor into the density calculation. 2. Stowability: Items that are more difficult to store will be given a higher freight class. This includes shipments that might be hazardous or very heavy. 3.
How can I determine the quality of my refrigerant?
You can find a two-phase diagram (like Mollier p-h diagram or other) for your refrigerant and if you know two independent properties of your refrigerant, you can identify quality X (% volume of vapour) and density. Other properties you can find with thermodynamic relations, like
