Consider a pumping scenario wherein 900 gpm of water at 80°F is transported. The inlet reservoir and outlet reservoir are open to atmosphere. The water level in the inlet reservoir is 3.4 ft above the pump centreline; the inlet has 6 ft of 4.9 in. nominal diameter of straight cast iron pipe (absolute roughness of 0.00080 ft), a standard elbow and a fully open gate valve. The NPSH required for this pump is 25 ft. As a design engineer, you have been asked to check if the pumping system will cavitate or not. Please provide an explanation.
