The Dubois library has an upper mechanical room and a basement mechanical room. The architectural plans show the floor elevation of the upper mechanical room to be 518' - 7 ½". The basement room has a floor elevation of 213' - 0 ½" . (elevations above sea level in feet and inches).
1. For a pump in the basement which must deliver water to a bucket on the floor of the upper mechanical room, what is the minimum pressure in psig you will see at the pump discharge.
What are effects of the annealing process on the density of these dislocations ? Can you give examples for materials?
