Abstract: In industries, organizations, and homes, liquids are conveyed for different purposes. It may be for industrial purposes or domestic purposes. The process involved in conveying liquid can make the liquid safe or unsafe for the purpose for which the liquid is intended to be used. Most industries use centrifugal pumps in pumping liquids. The use of centrifugal pumps in industries, organizations, and homes depends on the output pressure needed. Usually, the centrifugal pumps which are used for domestic purposes have a maximum capacity of four horsepower (4hp) as output power. the mass flow rate of water is different from that of diesel, engine oil, and hydraulic oil. Therefore, a centrifugal pump with a specific horsepower will handle each liquid differently, especially in relation to its volumetric flow rates. The study analyzed the volumetric flow rate of different liquids like water, hydraulic oil, engine oil, and diesel from a centrifugal pump of a specific capacity within specific periods. A volume of 40 m3 of one of the liquids under study was put into the bucket. The end of the hose connected to the suction nozzle was placed inside the bucket containing the liquid. The other end of the hose connected to the discharge nozzle was also placed into the measuring container. The pump was then switched on. The timer was connected to switch off the pump every 30 seconds. The highest volume of liquid that the pump pumped is water at a mean volume of 49.5860 m3. The mean volume obtained after performing the experiments on diesel is 48.0800 m3 which is lower than that of water. the mean volume of hydraulic oil and engine oil are 31.850 m3 and 25.8100 m3. The differences in the kg/m3 of the various liquid under study affect the velocity at which the liquids move when pumped. The head of each liquid is proportional to the mass of the liquid and the viscosity of each liquid is proportional to the volumetric flow of the liquid.Abstract: In industries, organizations, and homes, liquids are conveyed for different purposes.

Abstract: Aluminium is an important engineering material that is widely utilized due to its suitable mechanical properties in manufacturing industries. The effectiveness and efficiency of cast aluminium alloy depend greatly on various casting methods. The additives in the sand mould and quenching media contributed to perfect casting. Present study investigated the influence of various sand mould additives (Sawdust Ash, Groundnut Shell Ash, and Eggshell Ash) on the tensile properties of the cast Aluminium (6061) alloy cooled in different media (Water, Palm Oil, and Engine Oil). The additives were varied at 5%, 15%, 25% and 35%. After cooling, the samples were subjected to a tensile test and the result showed significant differences in the tensile strength properties of the cast samples. Ultimate tensile strength values increased as the percentage of additive in sand mould increased. However, for all the additives studied, water had the highest ultimate tensile strength values (107.52 MPa, 100.5 MPa and 94.55 MPa) followed by palm oil and engine oil at 25% but decrease at 35%. Percentage elongation values of the samples decreased with an increase in additives ratio up to 25% but had the highest values when quenched in engine oil. These observed behaviours are attributed rate of solidification the moulds and cooling rate behaviours of the media.Abstract: Aluminium is an important engineering material that is widely utilized due to its suitable mechanical properties in manufacturing industries.
