Casing burst load

Burst load This is the internal pressure the casing will be exposed to during operations... 

Step 3 Burst load (PJ. The burst pressure is equal to internal pressure reduced by the external pressure of the drilling fluid outside the casing. Therefore,... 

One of the big unresolved problems in detonation physics is that of the isentropic expansion of detonation products ie, there exists no completely acceptable relationship between expansion volume and pressure. Henry (quoted in Ref 27) assumed that detonation products expand radially with a linear velocity gradient. He also assumed a polytropic EOS with 7 = 3 (T in our notation) and that a cylindrically-loaded steel casing bursts at R/R0 = 1.2. At large R the casing approaches its full Gurney velocity, which... 

Bomb-ahelL A spherical or cylindrical case of iron loaded with powder, and burst by its charge on concussion or after an interval of time. See Shell. 

Bursts or puffs of smoke are produced by explosively-dispersing very fine particles (aerosols), either in the form of combustion products or as inert, solid ingredients. These effects are seen in daylight pyrotechnics displays or when firing blanks from artillery pieces. In the latter instance, a brass case loaded with grain gunpowder is fired from the breech to give white smoke, which is in fact an aerosol of mainly potassium carbonate particles. Alternatively, if a bag of fine powder such as charcoal dust is...
