Water in a hose with an area of 153 mm2 moves at 4 m/s, but then you cover part of the opening of the hose with your finger, and the water shoots out faster at 16 m/s . Find the area of the opening between your finger and the end of the hose in mm2.
Note: you can leave the areas in mm2 since they'll cancel out.
1. When the diameter (d 1 ) is double (refer to the figure above), what happened to the cross-sectional area or A 2?
2. What is the relationship between the cross-sectional area and velocity in the given diagram?
3. Water flows through a 2-cm diameter hose with a speed of 0.5m/sec. Find the speed of water through the nozzle if the diameter is reduced to 0.4 cm.
