Dear Isaac Wiafe Boateng
Quantum ESPRESSO can calculate pressures at a given volume (or volumes at a given pressure) of a given crystal. Solid-state Physics books (and also 
wikipedia, afaik) teach how to calculate the bulk modulus by using the quantities listed above. I'm not aware of automatic calculations of the bulk 
modulus, I'm afraid you have to sweat the old way for calculating the results...
