Web1 Feb 2011 · Sadovsky formula for positive shock phase duration for TNT blast wave: In this formula mass (m) is in kilograms (kg), and distance from origin is (r) in meters (m), resulted time is in seconds (sec). 5. Theory of blast waves shows that all other blast wave parameters are can be expressed as functions of overpressure. Formulas below Webwhere F 1 is the tension side force and F 2 is the slack side force. The quantity (F 1 - F 2) is the net obtained from the horsepower equation.For flat belts, the value of C is between 2 …

fluid dynamics - Calculation of force when shock wave passes

A mechanical or physical shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity). … WebExplosion (a definition) An explosion is the sudden release of energy into an atmosphere in which it cannot be contained, and as with shock loads this can be anything from 1 Joule … freshppo
