The permeability characteristics of sand depend on the size and connectivity of the pores in the sand. Water flows through the pores in a sand mass can be considered as laminar flow (Holtz et al., 2010). Therefore, in this study, the water flow in the sand is assumed to be a laminar flow in a vertical circular pipe (Fig. 11).

Explanation: In sand handling system of mechanized foundry, the moulds are taken out in a shaking manner that will allow the sand to be transported back to the conditioning plant through the conveyor belt. In this method, the process is easily accomplished without going into the various methods of sand handling.
Several factors can hinder the sowing process. Some studies suggest that variability in weather or soil conditions and the mechanized systems utilized or quality agricultural opera-tions can create issues during the sowing process [5]. Sandy soils are recommended for peanut cultivation [6] since high porosity provides better

Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep mines of the day. Early lighting systems were of the open-flame type, consisting of candles or oil-wick lamps. In the latter type, coal oil, …
