Abstract:
These project focuses on improvement of fire nozzle design in areas of minimize the backward thrust of fire nozzle and optimization of water flow system for fire fighter in Malaysia. Fire nozzle is one of the important tools used by the fire fighter in order to extinguish a fire. Every aspects starting from the type until how to handling the nozzle is important for fire fighter because there are several types of nozzle and each one of the nozzle has different use based on the situation of the fire. Nowadays many fire nozzles have been produced to fill customer purpose in order for the fire fighter to extinguish the fire more effectively. However, there is still problems arise when the fire fighter shoot out the water from the nozzle, where the backward thrust happen and this problem is dangerous for the fire fighter. In order to overcome the problem, the absorber is created to minimize the backward of the nozzle. One of the major problems occurs when the fire fighter try to extinguish the fire is low water pressure from the fire hydrant. Low water pressure seriously affects the performance of the fire fighter when they want to put out the fire and slow down the process to extinguish the fire. To optimize the performance of the nozzle even in low water pressure, one spring and baffle is put in the nozzle to optimize the water flow of the nozzle.
