Absorption & propagation of energy from blast

If an explosion occurs, it causes rapid increase of pressure in confined / pseudo confined space resulting in damages to structure / walls confining the space. Thereafter, as the confined space is exposed at one or multiple locations, blast waves propagate through adjascent media through speed of sound.

If the above are true, my questions are:
1. How can we assess the energy content of such blast waves? (e.g.say, a mixture of 1 L volume at NTP with 10% hydrogen & 90% air explodes)

2. Assuming that the confied space is actually a 2 m dia x 100 m long pipeline (MS 8 mm thick) open to atmosphere at both ends and explosion occurs at the centre of the pipeline,

(a) What will be the maximum pressure of blast wave ?

(b) How much energy is transferred to the walls of the straight pipeline?

(c) In case there is a 90° bend 10 away from the blast centre, what amount of momentum is transferred from the blast wave to the pipeline? What is the energy absorbed by the pipeline in that case?

(d) How much energy of a blast is absorbed by a 1 m x 2 m plate located perpendicularly to the line joining the centre of the blast and the centre of the plate (i.e.maximum blockage possible) and located 3 m away from the blast centre? How much energy is reflected? How much can possible be transmitted is the plate is horizontal initially and is loosely placed on support of negligible dimensions?

I will be grateful if someone or many person can contribute collectively to answer the question......Thanx
