Artificial Water Hardness RemovalModelling and Simulation in ASPEN Plus , 2023

However, the study herein shows that the software can simulate a simple hard water softening plant, a phenomenon that is important for home and industrial use. Three m 3 of artificial hard water containing 288 kg CaCl2, 390 kg NaHCO3, and 220 kg of MgSO4.7H2O was softened by passing it through different units defined using ASPEN Plus V8.8. The initial mole percent of the hardness chemicals added was 12.84 %, resulting in soft water containing trace amounts of all the hardness chemicals. Separation of the minerals from the hard water was achieved using an evaporator unit 'Flash2', where the temperature above the boiling point of the compound or mineral salt with the highest boiling point was specified. Almost 100% soft water was achieved when the simulation converged. This work, therefore, addresses the potential negative effects associated with the use of hard water by humans and animals. Engineering such a scheme for implementation across all water treatment facilities would be a welcoming idea, as it will help reduce the challenges faced by end-users of clean hard water supply.

To analyze the pump performance, ANSYS student version 2022 software was usedwherein; head rise (H), pump speed (N), discharge rate (Q) and inlet pressure of 20-120m, 2000rpm, 144m 3 /h and 0 atm were respectively specified as initial and boundary conditions in the computational fluid dynamics (CFD) tool. CFD for inlet and exit blade angles of 35 o , 38 o , 41 o and 47 o , 50 o , 53 o were respectively simulated for all fluid type using a 7bladed impeller to obtain contour plots and pressure and velocity distribution results of the analysis. It was deduced that the overall efficiency of the centrifugal pump depends on the outlet blade angle and fluid type, while the power used rises with both inlet and outlet blade angles. Further studies should be channeled towards analyzing the variations in N, Q, H, impeller blade number (Z) and its width, for this particular type of impeller.

This study was motivated due to the fact that students in colleges have been having problems in Physics Practicals which subsequently lead to poor acquisition of practical skills and under achievement in physics. Laboratory practical is an active ingredient in the teaching and learning of physics that leads to the acquisition of physics concept and scientific skills. This makes the production and development of quality professionals in the field of sciences, especially physics, a vital tool in achieving sustainable economic growth and technological development of the nation. The design used in the study was quasi experimental design. A sample of (60) NCE 2 students out of a population of 85 students in Physics Department College of Education, Azare Bauchi state were used in the study.
