Question

The equation for peak particle velocity (PPV) from blast induced ground vibration is given by

PPV = k \left( \frac{D}{\sqrt{6}} \right)^B,

where k and B are site constants.

In a field study, the following readings are recorded.

Sensor No.	PPV in mm/s	Sensor distance from blast site (D) in m	Charge per delay (Q) in kg
1	5.5	200	100
2	3.4	300	100

The value of $B$ is ______ (round off to 3 decimal places).
