Caslcafe Sdn. Bhd. is a local brewery company that produce high quality grape wine from grapes that sourced from Cameron Highland. During the production of grape wine, the first step will be the anaerobic (without C:) fermentation of grapes in an underground fermenter using wild yeast. Indeed, the fermenter is buried underground, but it has a venting valve that allow the continuous escape of fermentation gases to the atmosphere. After 136-h fermentation, 35°C, and heat capacity 4.3 kj/kg- raw grape wine (specific gravity = 1.16, temperature %3D K) will be delivered at a flow rate of o.021 m/s from a underground fermenter to a conditioning tank via a pump, which powered by an electrical motor. The pump joins 2 pipe sections with different sizes, specifically suction pipe (diameter-15.71 cm) and discharge pipe (diameter 7.66 cm). Initially, both pump and motor that procured from ProTech Sdn. Bhd. have 100% efficiency.
