The Ball's formula was implemented to determine heat penetration parameters with slowest heat penetration data and to compare Ball's parameters at F 0 values of 6.0 and 3.5. An F 0 of 3.5 was selected for further analysis based on referenced literature provided by a thermal process authority that provided a lethality F 0 value of 3.5 ( National ...

Speed is the distance traveled divided by the time of travel. For example; if you were to travel a distance of 10 miles in 2 hours time, then your average speed equals 5 miles per hour. s=d/t (s=speed, d=distance, t=time, and the / means to divide). The word velocity is very similar to speed (except velocity also has a direction called a vector) and in most cases we will now use the letter "v ...
