Elijah Reaper joins the volunteer fire department.  Out practicing his fire hose prowess one day, he attempts to master stabilizing his body while blasting water.  He holds the spray nozzle perfectly horizontal, 2 meters up from the ground, and its diameter is 10 cm.  He finds that his body and strength can only withstand a moment about his feet of 50 Nm to continue holding the hose securely.  What is the maximum volumetric flow of water (m3/sec) that the hose can spray for him to remain standing

Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.
