What is the K factor in blasting?
K-factor – A scaling factor correlating the distance (D) and Net Explosive Weight (W) with a particular peak incident overpressure based on the Kingery-Bulmash relationship, as shown in Figure 1.

What is ESQD arc?
The ESS software is a Geographic Information System (GIS) software application that automates the calculation and display of Explosives Safety Quantity Distance (ESQD) arcs for explosives storage or handling sites. ESS software tools are used to assist with the development of site plan maps and packages.
How do you calculate K factor?
We calculate k-factor by dividing t by the material thickness (Mt): k-factor = t/Mt, The k-factor is nothing more than a multiplier that can give you an accurate value for the relocated neutral axis. And if you know the bend allowance, you can extract the k-factor from it.
What is net explosive?
The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc.
What is a good K-factor?
From discussions with other entrepreneurs, investors, and growth hackers, I’ve learnt the following: for a consumer internet product, a sustainable viral factor of 0.15 to 0.25 is good, 0.4 is great, and around 0.7 is outstanding.
What is the purpose of Intermagazine distance?
1 Intermagazine Distance (IMD). The IMD to protect against the prompt propagation of an explosion of Class/Division 1.1 material between magazines is provided in table 2-1 of reference (1).
