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.

4. The system in Fig. consists of 1200 m (length) of 0.05 m (diameter) cast iron pipe, two 45° long-radius elbows, four 90° flanged long-radius elbows, and a fully open globe valve.

A pump is used to take water out of a large lake and deliver it to a farm to be used for irrigation. The pump location is illustrated in the figure below, where the suction side of the pump (also called the pump intake) is 3 m above the water surface in the lake and the vertical intake pipe has a diameter of 150 mm. (Discharge side) Pump - >100 L/s P (Suction side) 3m -150 mm Lake Part A Assuming that viscous effects are negligible, what is the pressure on the suction side of the pump when the flow rate through the system is 100 L/s?
