A garden hose is connected to raise a narrower hose wherein the diameter of the bigger is twice the diameter of the narrower hose. The fluid flowing is a fresh water having an entrance velocity of 1.2 m/s and a pressure of 143 kPa find the the pressure in KPa and velocity in m/s at the exit point. Note; h or Ay = 20.0 cm (Express or round off your answer to one decimal place.) 20.0 cm Answer:
A centrifugal pump driven by a 120-kW motor rotating at 2400 rpm is used to pump 20°C water in a manufacturing plant. The pump operates against a head of 30 m and has an efficiency of 70%. If this pump is situated 9 m below the level of the source, calculate (Zs)max and determine if the pump is safe from cavitation. Select one: O a. -7.9 m; NOT SAFE O b. -9.7 m; NOT SAFE O c. -7.9 m; SAFE O d. -9.7 m; SAFE
