Laser ablation propulsionis powered beam propulsion in which a pulsed laser ablates the target materials(solid or liquid) and then producing thrust. By the resultant force ofreaction, the thrust produced on the target surface. The laser ablation propulstionis use to study the specific impulse, momentum coupling co-efficient (Cm),efficiency and thrust. The laser ablation process and propertieshas …

ABSTRACTThis paper reports the potential of watermelon seeds and other cost-effective materials in purifying impure water. It is aimed at minimising the usage of alum and other polyelectrolytes in the process of purification of water while increasing the usage of watermelons seeds which is identified as a potential coagulant for water treatment. The resulting value …
